Excellent post. The pictures explain it very clearly

At first glance the flight feathers look spangle but if you just at the top half of the bird it doesn't look spangle at all. I still think that it is a yellow face grey cinnamon dilute

Usually if a pied bird has clear flights and no clear band on the front it is a clearflight pied. The clearflight pied gene is inherited in the same way as the dominant pied. The picture is not clear enough to tell Storm's mutation. Dominant pieds can be split for recessive piedhi Elly. Looks like we posted at the same time

I think that the chick is a mauve recessive pied in spite of the white flights. Recessive pieds have random markings and in this case the marks have missed the flight feathers. The white area on the front is very high which is an indication of a recessive pied. The clear patch on the back of the head is common to all varieties of pied. If it was a combination of both pied types you'd expect a lot less markings

It is very difficult to stop at 50 birds because the tempation to retain another and another is very strong. Every breeder has their own ideas on what works best but the most important thing is to keep good records of your birds so that sound decisions on pairing can be made. With only a relatively small number of birds it would be difficult to maintain many separate lines and you probably will need to import partners sometimes. Some breeders are cautious about pairing albinos together but if the birds have good points these can be enhanced in the same way as the good points on any other mutation

Your hen is a yellow face grey and your cock is green opaline dominant pied. Half the females would be opaline dominant pied and the other half ordinary opalines. The male chicks would be half each of dominant pied and normal. If the cock is not split for blue the chicks would all be either green or grey green If the cock is split for blue you would also get blues and greys, with half of them showing yellow face Of course if the birds are split for some other recessive mutations you could get a few surprises

Sky is a is not dominant pied he is a greywing clearflight pied. He has no clear band on his front which a dominant pied would have. He looks like he may have some sexual health issues judging by his cere Cloud is a recessive pied. He also appears to be male unless he is quite young If they are both males then obviously no predictions about offspring can be made. If a male and female with the same mutations as your two were paired to gether half the chicks would be clearflight pieds and the other half normals. Recessive pied and greywing are both recessive mutations so the partner that was not showing the mutation would need to be split for it before you would get either mutation

I have an opaline that was very heavily marked like this one and when it was 3 years old all the markings disappeared and it was left with a nice clean head

I think that this chick will be nice when it grows up. It is a sky blue opaline spangle. The 3rd picture shows it's parents, they are an albino masking spangle hen and an opaline cobalt cock. They have 2 other chicks which are both mauve opalines. As opaline is a sex linked mutation the chicks will all be female unless the albino is also masking opaline

I agree, it is a dark green opaline

In the 1st picture you have 2 recessive pieds on the left and centre. The 1 on the right could be a spangle but I would need a picture showing it's wings to be sure 2nd picture looks like a mauve on the left and possibly a greywing (picture doesn't show enough to be sure) 3rd picture: If they have red eyes you have a creamino and an albino in the nest 4th picture is an opaline cinnamon

I agree that they are creaminos (type 2 yellow face albinos). They are a very popular colour, definately not rejects

It's a boy. As it is a recessive pied it's cere will stay pink and never go blue like the males of most other mutations

Sky blue dilute (could also be opaline) Light green opaline Texas clearbody Sky blue spangle Sky blue recessive pied dilute

CONGRATULATIONS

I agree that your bird is a type 2 yellow face cobalt spangle. When he is old enough if you paired him with a normal blue hen you would get about 50% spangles and 50% normals. half of each type will be yellow faced. There are numerous possibilities if he is paired with some other mutation

It sounds like the problem could be weak shells on the eggs. Do the birds have a good supply of calcium? Other possibilities are as Kaz mentioned: the age of the birds or the nest box design. The birds all look very young in the pictures or perhaps they are old pictures

Not possible yet, but who knows what the future holds

Don't know, but the yellow is very bright To be a double factor type 2 yellow face both parents would have to be T2 yellow face. Usually double factor T2 yellow face birds show less yellow than single factors

Assuming she has red eyes. She is a type 2 yellow face albino, usually referred to as a creamino

Remove the nest for a couple of weeks then try again

I'd say 3 hens too

She is a grey dilute

The 1st chick doesn't look spangle to me. I'd say it could be yellow face grey cinnamon dilute The hen and the 5th chick don't show opaline. They are both grey cinnamons The cock bird must be split for opaline and cinnamon, and both must be split for one of the dilute mutations
