I went on vacation and seem to have come home to a roo. His comb and wattle are definitely more red and look at those saddle feathers! The black pullet is his hatch mate.
Multiple roosters, so I'm not sure.
The comb and wattle developed early so I was 99% sure cockerel, but there's been no further development for a few weeks. I had some chicks hatch four weeks after this one, and those cockerels had combs that grew faster and even a little bigger than this...
Seems like a barred rock mix of some sort, but probably not 100%. He/she is a Barnyard mix my buddy gave to me as an egg when I had a hen go broody and wanted to see her try to hatch her own babies!
This chicken is 11-12 weeks old and I'm hoping it's a she. Its comb is bigger and pinker than its hatch-mate, but they're clearly different breeds. The comb hasn't changed or grown for the past few weeks. No crowing, although I've heard crows from a younger batch of hatchlings.
