The hen is an opaline dominant pied and she must be split for recessive pied because the chick on the left is a recessive pied. The white chick is probably a combination of recessive pied and dominant pied (the yellow next to it could be the same). She must have mated with a spangle to produce the chick on the right but he may not have been the father of all the chicks.

Pair 1: I think the hen is yellow face sky blue not cobalt. If neither bird is split for anything, and the yellow face is single factor, they should produce about 50% each of sky blue and yellow face sky blue. The cock bird is showing opalescence which is often a sign that he is split for opaline. If he is split about half the female chicks will be opaline Pair 2: Assuming the cock is single factor grey you should get greys, blues, yellow face greys and yellow face blues in about equal numbers. About half will be spangles. The opaline from the hen will only show in the chicks if the cock bird is split for opaline Recessive or sex-linked mutations could appear from either pair if they are carrying hidden genes

It is not unusual for a male double factor dominant pied to have a pink cere like a recessive pied. I have never heard of a recessive pied with definate iris rings like this bird. As he is marked so much like a recessive pied I think the only way to be sure is to breed him and see what he produces

He is a clearwing spangle. The frosting on his rump is very common in spangles and when clearwing is combined with spangle sometimes the markings are so faint that the frosting it the only visible sign of the spangle mutation

The 2 greens are both opaline The next 2 are a sky blue recessive pied and a normal sky blue (the spot indicates that he is split for recessive pied) The last picture T2 yellow face opaline greywing sky blue (but need a better picture to be sure about the greywing part). And a sky blue recessive pied

Congratulations on a great photo

The white budgie appears to be a double factor spangle, if she is all the chicks will be blue spangles. If the hen is split for recessive pied the spangle will combine with recessive pied on about half of the chicks The only way there could be any albinos would be if the cock bird was split for albino

Knowing the parent's of our birds can help a lot when predicting the offspring but recessive genes can be carried for many generations the pop up unexpectedly when paired to the right mate. Usually it much easier to tell what colours or mutations a pair can't produce. Here are a few examples: A pair of blue birds can't produce a green chick A pair of normals can't produce a dominant pied or any other dominant mutation A pair of opaline's can't produce a normal A lutino cock can't produce any female chicks that are not either lutino, albino or lacewing A non-opaline hen cannot be the mother of a male opaline chick

I agree

The expected result from mating a recessive pied to a dark eyed clear would be about 50% recessive pied and 50% dark eyed clear. The 2 chicks look recessive pied with another mutation like cinnamon or greywing lightening the markings Dark eyed clears can mask other mutations like spangle but neither of the 2 chicks look spangle to me.

A lutino clutch - the one on the right is a lacewing

1/ opaline sky blue 2/ opaline dark green 3/ Type 2 yellow face cobalt 4/ yellow face recessive pied cobalt 5/ yellow face cobalt 6/ recessive pied olive (looks like a yellow face grey but can’t see grey in the parents) The father of the two chicks could be either 4 or 3 but could not be 1

A blue budgie lacks the yellow melanin that would make it green but the yellow melanin is not quite the same as violet which is a colour adding factor. Inos are lacking all melanin except the base white or yellow Yellow face budgies are often described as being between blues and greens, but it is not as simple as this because, if they were it would be possible to breed a green budgie from a yellow face blue, but you can't. The gene that causes the yellow face is a different gene from the one that makes a green Selectively breeding for a particular trait will not create a new mutation. New mutations are caused by changes to the sequence of the genetic material. They appear because of copying errors in the genetic material during cell division, or by exposure to radiation, chemicals, or viruses

There is no doubt that your bird is male. He is an opaline sky blue

A double factor spangle that is masking recessive pied will usually have no iris rings, an orange beak and the males usually have a pink cere. They can easily be mistaken for a dark eyed clear until they are bred and produce spangle chicks

A recessive pied spangle or perhaps something really rare like a mottled spangle

Congratulations. Great picture

Look like a male

J T – Dark green normal Grace – Grey normal Boo – Spangle cobalt (many splangles have a clear patch on their heads) Lacey – Cinnamon greywing light green (could be a dilute but looks more like cinnamon greywing) Cindy - Yellow face cinnamon opaline dominant pied grey Budda – normal light green Alice – Sky blue normal (split for recessive pied) Droopy loo loo – Not sure needs a better picture but could be a yellow face dilute Austin – Yellow dark eyed clear

He is certainly not a normal green. It is a pity that he doesn't have more flight feathers so we could see what they were like. Birds that are split for recessive pied can have pied spots as large as his but they would not have other clear areas. Judging by the clear areas on his tail and chest I think he is a clearflight pied that is not very well marked. Dominant pieds are usually less variable than clearflight pieds

Congratulations

The dark factor works totally independantly of the mutations. A bird with 1 dark factor mated to a hen with no dark factor will produce 50% with 1 dark factor and 50% with no dark factor. The mutations, whether they are sex-linked, dominant or recessive will be inherited according to the rules of each individual mutation

Budgies are very fickle. In a colony breeding situation with several pairs it is not uncommon for 1 or 2 cock birds to father all the chicks even when the hens are bonded to other cocks

Looks like a normal sky blue, the others look like normals too. A pair of spangles would be expected to produce about 25% normals, 50% single factor spangles and 25% double factor spangles
