All three yellow face types are dominant so mating a single factor yellow face of any type to a normal will produce about 50% yellow face chicks. The gene works the same way whether the birds are blue or green but of course most times you can't see if green birds have the mutation or not Because a double factor type one yellow face is a white faced bird it is often claimed that the yellow face is split but this is not correct. When a double factor type one is mated to a normal it will produce 100% yellow face chicks. If the gene was just carried as split it would have to come from both parents and then would only produce about 25% unless one parent showed the mutation visibly The other thing that should be remembered about yellow face types is that a bird can be more than one type. Generally golden face will mask either of the other types and type two will mask type one I have also seen genetic programs that show yellow face as split, it shows that the writer of the program did not have a proper understanding of how the gene works

Here's one. The cinnamon is not obvious but as her father was a cinnamon it is definately there

I agree with Liv but although the second chick looks like a type 1 yellow face it is really too young to tell because the yellow often doesn't spread until the 1st moult. It's yellow face type will be the same as the parent it inherited it from unless that parent is a type 2 that is masking type 1

Light green opaline greywing. The greywing gene dilutes the body colour, a dilute would be quite a bit paler

I don't know how I missed this thread back in June. Millie is a grey green opaline spangle. In the first picture the opaline is not very obvious because she is heavily flecked and the markings are dark, but you can see it. Flecking on an opaline chick often moults out. The dark markings are probably caused by the grey factor she has inherited from her father. Millie's father appears to be a grey green opaline dilute. He is definately opaline so all his daughters must also be opaline. Millie's sisters that are pictured here are certainly opaline

A double factor spangle mated to a normal will produce 100% single factor spangle chicks. Mating him to the yellow face grey will produce Grey spangles Yellow face grey spangles Blue spangles Yellow face blue spangles If other mutations appear they will combine with the spangle

Yellow face opaline greywing. The yellow is not bright enough for a golden face

I agree with the others. Sparkle – Cinnamon grey green male Cosmic Dust – Normal cobalt male Storm – Normal grey male Mermaid – Opaline sky blue female Visions – Dominant pied cobalt female

Lucy is an opaline dominant pied light green Horton is a dominant pied dark green Nibler is dominant pied light (I think) green Simone is dominant pied cobalt Stewart is a double factor dominant pied cobalt Colbert is dominant pied dark green Xena is dominant pied sky blue The usual expectation from mating two dominant pieds is 50% dominant pied, 25% normal & 25% double factor dominant pied Opaline is a sex-linked mutation. Because your hen is opaline all the male chicks will be split for opaline. For opaline to be visible in the chicks the cock bird must have genes for opaline Both parents must have genes for blue to have produced blue chicks. The reason you have different shades is because of the dark factor. The cock has 1 dark factor and the hen has none so their half chicks would be expected to have 1 dark factor and the other half no dark factor. Sky blue and light green are no dark factor shades, cobalt and dark green are 1 dark factor shades. Here are links to some simple rules about genetics I wrote for beginners that might be of interest http://www.officialbarrieshuttbudgerigars....legenetics1.htm http://www.officialbarrieshuttbudgerigars....legenetics2.htm

The best tip I can give you is to read the information in these links http://forums.budgiebreeders.asn.au/faqs/i...&artlang=en http://forums.budgiebreeders.asn.au/faqs/i...=show&cat=8

Meadow – Opaline light green female Splotch – Photo is not good enough to tell, but could be a dark green opaline dominant pied Summer – Spangle sky blue female Topaz – If she has black eyes she is a double factor spangle. If she has red eyes she is a lutino Lonesome – Dominant pied dark green with a violet factor OR a type 2 yellow face dominant pied cobalt – a picture showing more of her body would help

Candy is a double factor spangle cock - The blue cere gives his mutation away Fansy is an opaline dominant pied light green hen Chow is type 1 yellow face cobalt hen

Thats right. Paired to a lutino you'll get about 50% inos of both sexes. About half of the inos will be masking spangle and half of the non inos will be spangles

Thank you all for your comments. I took about 20 photos trying to get this one

I have been adding millet sprays and seed to the nest boxes ever since reading Kaz's first post on the subject. The results are excellent, all the chicks can feed themselves by the time they leave the nest

The throat spots look brown to me. I agree with Dean, opaline cinnamon recessive pied sky blue

1/ Yellow face dominant pied clearwing sky blue 2/ Looks like a dilute but can’t be sure 3/ Dominant pied greywing (or cinnamon) cobalt 4/ Dominant pied greywing sky blue 5/ Dominant pied greywing (could be green but looks more like a yellow face blue) The bird in the last picture is a clearwing opaline sky blue

Sorry I really can't suggest anything that will help. I hope that you can find out what is causing the problem before it is too late. Have the vets opened so that you can take him for their opinion? Good luck

Most of my breeding cages are inside the aviary and I've had no problems. The breeding cages are quite large so the birds don't feel trapped. If a hen is ready for breeding she is not interested in escaping and the cock bird should be interested in the hen

A cinnamon cock to a lacewing hen will give you cinnamon cocks that are split for lacewing and cinnamon hens

Cielito – Type 1 yellow face recessive pied violet sky blue Sonny – Type 2 yellow face dominant pied cobalt Zu-zu Opaline spangle dominant pied sky blue Nixie – Type 2 yellow face opaline cobalt (don’t think she’s violet) Violet is always difficult to be sure about in photos but although a purple hue showing around the neck is usually a sign of violet every bird with this effect is not necessarily violet.

The yellow face gene has nothing to do with the dark factor so you won't loose anything The 2 birds you have pictured are different types of yellow face . The first one is a type 2 and the second is type 1 so breeding them together will not produce any double factor yellow face birds. The result should be about: 25% type 1 25% type 2 25% combinations of the two types but the type 2 will mask the type 1 25% normal white face
