She’s very pretty! Her tail is much bigger than my one! After seeing your Pinto, I think mine looks more masculine

Hi everyone, so I’ve had another theory come to light: this chicken is a barred rock from two dark barred parents. The white is recessive. This fits with breeders claims that pens are secure. Thoughts? Chicken is now 12 weeks.

Yes, I think that explanation can cover all of what we know so far.

If that is the case, I would think the has barred and silver (both are normal in Barred Rock flocks), but has E^Wh Wheaten at the e-locus, where Barred Rocks are supposed to have E (Extended Black.) Because E is dominant, there could be a rooster and a hen that have E and show it (so they look like normal Barred Rocks) but carry E^Wh (so that pair produces about 1/4 chicks like the one you have.) I would guess only one hen in the pen carries it, because otherwise these chicks would popping up often enough that the breeder would have noticed it. But if all the other hens are E/E (pure for Extended Black), then all their chicks would look normal, although about half of the chicks would carry that recessive-- so depending on which chicks get selected for next year's flock, that breeder could have large numbers of off-color chicks next year, or they might not have any if they pick a rooster that has E/E so every chick will show E.

You are incredible! I’m so impressed with your knowledge thanks for always offering your expertise

Here he/she is at 17 weeks. She’s very big- massive feet! Her feet are bigger than my 10month Ancona’s feet.
That being said- is she still looking like a pullet?

 

[PimsGarden]

Yup, still would bet pullet!

 

[SilverBirds]

Yes, she's for sure a pullet now.

At 17 weeks, yes I think pullet.

Did the breeder also have meat birds? Like White Cornish or X-Worth?
