Daz, thank you for sharing this as many others have already said... it helps to learn from not only from your own mistakes but from others as well. And by sharing you've enabled others not to follow the same mistakes.. my appreciation to you for doing that. It also brings up a good point if you have similiar situations of birds suddenly going sick or dying to make sure to have them checked out and the autopsy to find any diseases and/or find out what can be changed in your management program that can avoid the issue in the future and possibly save your remaining flock. Well done to you for your proactive response to the situation and finding the root cause. As you've said before, even the good breeders have something to learn every now and then... nothing is set in stone and often times we need to take a step back and re-evaluate why we do the things we do or the way we do them. In your case it wasn't necessarily what you were giving them but the effects of the dosage in relation to the bird's environment/activity.

i agree, YF2 Recessive pied sky.... not an opaline... many rec pieds will be missing those markings as normal.

I've used that site in the past but after doing some in depth research found some discrepencies on that site that are not accurate or simply missing. Elly is correct... if they have the V pattern and the body color bleeds into the wings, it's an opaline.

a yellow & blue pied would have yellow replacing the white pied areas with yellow on both GF and YF2 birds... so it would be considered a white-based budgie.

aaah okay that's better yes I thought it was just bad photo... you're right of course it's a opaline spangle violet sky :hap: I even made an article based on your example on my website ... it was a good genetics example lesson... although complex for the beginner.

yes there is a visual difference... (works the same as the YF2) in showing how it bleeds based on SF or DF... post a photo and we can tell you what type it is

I have a photo of one of my violet greens for you guys... it's funny because in person it looks like an "odd" olive (the father was a light green and the mother was a violet cobalt)... so olive isn't a possibility as the father has no dark factors. I've discovered a confirmation to something I heard once in how to tell if you have a violet green as it shows up in photographs with a flash differently than to the eye when they are carrying violet, in the photo you can see the "blue/violet" comming through the green... here is the photo of my violet green.. here he is without the flash.. how he looks to the natural eye: here is a photo with the flash, and you can see how the violet is in the green (chick in the middle):

I haven't read the entire thread yet, but just for a quick reference there is only YF1, YF2 and GF... no GF2 exists. The GF acts similiar to the YF2 in how it bleeds into the body. If you go to my mutations page on my signature link, you can see photo examples of the single and double factor of all three types which may help you. As far as inheritance of a GF to a whiteface, if the GF is single factor you'd get 50% GF, 50% white face.... if the GF is double factor, you'd get 100% GF chicks. Don't forget that white faced blues can genetically be 2 different types... either a "true" whiteface or a double factor YF1. This may affect the outcomes of your chicks if it is actually a YF1 double factor because he will throw 100% YF1 single factor chicks into the mix.

yep you're right he's a sky violet but looks like a YF2 in the photo or is that just bad lighting? not the best photo so doesn't look like an opaline spangle markings in it.. but I know sometimes photos can be off... if I'd just seen this photo I'd have said clearwing instead.. and no body color showing in the V-neck or wings that I can see which would be the opaline... but like I said could be just the bad photo.

if one is a sky and one is cobalt... why are you saying violet? are they a sky violet and a cobalt violet (visual violet)? so assuming that the cock is actually an opaline spangle sky violet (single factor), and the hen is a spangle violet (aka cobalt + violet single factor): dark factor color for both genders: /dominant inheritance 50% sky (0 dark factors) 50% cobalt (1 dark factor) violet factor for both genders: /dominant inheritance 50% single factor violet 25% normal (non-violet) 25% double factor violet spangle for both genders: /dominant inheritance 50% single factor spangle 25% normal (non-spangle) 25% double factor spangle opaline by gender: /sex-linked inheritance 50% female opaline 50% male normal split to opaline so add those mutation percentages together and you get the following genetic possibilities (which don't include any possible hidden factors your birds may be carrying in hidden form): ...note that the percentages are purely statistical percentages of possibility based on the above genetic percentages... 1.5625% - sky normal /opaline cock 1.5625% - sky normal opaline hen 3.125% - sky SF spangle /opaline cock 3.125% - sky SF spangle opaline hen 1.5625% - sky DF spangle /opaline cock 1.5625% - sky DF spangle opaline hen 3.125% - sky SF violet normal /opaline cock 3.125% - sky SF violet normal opaline hen 6.25% - sky SF violet SF spangle /opaline cock 6.25% - sky SF violet SF spangle opaline hen 3.125% - sky SF violet DF spangle /opaline cock 3.125% - sky SF violet DF spangle opaline hen 1.5625% - sky DF violet normal /opaline cock 1.5625% - sky DF violet normal opaline hen 3.125% - sky DF violet SF spangle /opaline cock 3.125% - sky DF violet SF spangle opaline hen 1.5625% - sky DF violet DF spangle /opaline cock 1.5625% - sky DF violet DF spangle opaline hen 1.5625% - cobalt normal /opaline cock 1.5625% - cobalt normal opaline hen 3.125% - cobalt SF spangle /opaline cock 3.125% - cobalt SF spangle opaline hen 1.5625% - cobalt DF spangle /opaline cock 1.5625% - cobalt DF spangle opaline hen 3.125% - cobalt SF violet normal /opaline cock 3.125% - cobalt SF violet normal opaline hen 6.25% - cobalt SF violet SF spangle /opaline cock 6.25% - cobalt SF violet SF spangle opaline hen 3.125% - cobalt SF violet DF spangle /opaline cock 3.125% - cobalt SF violet DF spangle opaline hen 1.5625% - cobalt DF violet normal /opaline cock 1.5625% - cobalt DF violet normal opaline hen 3.125% - cobalt DF violet SF spangle /opaline cock 3.125% - cobalt DF violet SF spangle opaline hen 1.5625% - cobalt DF violet DF spangle /opaline cock 1.5625% - cobalt DF violet DF spangle opaline hen ....all of which could be changed if there are hidden factors that were not known, or if one of the birds is a double factor violet instead of single factor violet... or that they are not in fact both carrying violet.

looks like a type 1, as I don't see any bleeding into the white areas on the wings or into the chest area... However the first molt will confirm this as with type 2 the yellow will progressively spread through the body with each molting.

well some photos for you guys.... chick 1 - grey violet spangle chick 2 - cinnamon grey chick 3 - grey opaline chick 4 - spangle grey chick 5 - spangle grey From this test breeding, we found that Dusk is double factor grey and is split to cinnamon and opaline. (already knew about the cinn, but the op was a surprise and knew it was possible for the df grey since both parents were grey, but had to test breed to check)

My bird room is located in the basement (with windows). I keep mine between 65-75 F all year round depending on the season. Generally as long as it's not cold enough to freeze the water, they'd be fine though... it's not the cold so much as the quick change in temperatures that harms the birds in my experience... if the temperature is gradually changed then I've had no major issues.

I agree with Nerwin, a sky greywing will have the color effect shown on your budgie.
