Yes, I will list all the genotypes I can think of to produce a white phenoytype:
Recessive white:
c/c + anything else
Typical Dom white:
E/(any E locus), I/I
White Silver Birchen:
E^R/ E^R, I/I, S/S
White Silver Wheaten ???: E^Wh/E^Wh, I/I, S/S
White Silver Partridge:
e^b/ e^b, I/I...
Blue and black from two paints or partridge from a blue and black?
Either way is possible, 2 paints have a 25% chance of solid non white colour.
A blue and black could both carry partridge and have a 25% chance of producing partridge chicks.
Yes, if both paints were heterozygous for extended black and partridge, there’s a 25% chance you get partridge, half white partridge, which will be faintly coloured like my white chick with buff stripes, the others normal (or blue/splash if they are blue paints).
It’s probably a waiting game, as much as I’d like to think of a solution I’m not entirely sure on what genes are at play, this will become more apparent when older .
I
just realised that silkies have both types of white, not just dominant white. My rooster must be recessive white, with partridge underneath, and my the hen must be E/e^b, blue and I/i+ (blue paint).
I never realised most whites were receive white, I just assumed they were all dominant white...
I thought you’d find this entertaining:
I’ve just hatched four of my silkies, they are from a ‘pure white’ cock in with three paint hens. I got two whites, one white with buff chipmunk stripes, and one blue partridge. I can’t figure it out at all, how would a pure white have non white/paint...
Jeeeeeeze!
Let me get back to you tomorrow, I need to do some thinking. It seems we have to think about the E locus now, and Co/co too because of the red. Is it just the frizzle’s chicks that aren’t solid Blue, Black, White or Splash?
That is an option too, but you can definitely get no dom white by using your splashes too, it depends if you want to wait for them to grow and then their chicks to grow or if you’d rather just change roo straight away. The blue and splash thing isn’t a big deal as long as we have recessive white...
Your splash chicks are, assuming you don’t end up with partridge or Columbians (this won’t matter as rec white masks all pattern and ground colour):
E/E (self colour), i+/i+ (wildtype, not dom white), Bl/Bl (splash), C/c (heterozygous rec white, not showing) that’s all that matters for this...
This makes a lot of sense (this is what I meant when I asked, I wanted to know which ones were related). That means is probably the rooster that is heterozygous for dominant white, and the hens must be whites that were bred from or with blues at some point, and you’ve ended up with splash and a...
This makes the most sense from the data we have. The only thing I’d say is it seems strange for all the parents to be atypical genotypes. Where are the different bloodlines from?
Yes, anyone you have contact with that hatched your eggs. Just as big a sample size you can get. Record total number of chicks, and then the number of each colour.
This is a recommendation, you don’t have to if it’s a lot of work
This is Boots, she is a solid blue Brahma but the first covert feathers grow in looking barred. She was a lot darker as a chick than yours though, the colour of her down here is pretty much as it was when she hatched.
The feathers look blue to me, they can appear striped as they grow in, I’ll try to find a picture of a blue Brahma if mine for reference. It’s strange that they look so pale though. Lavender might also be an option, but it will be a waiting game. If it’s not too much bother, would you be able at...
