4 weeks old, we have only our list from MMcMurry Hatchery to go by, and all your BYC expert advice and pictures to guess what our 26 chicks are. The only reason we didn't guess cochins, is we have two really fluffy buff chicks that compared to these feathered friends weren't as poofey. Now their feathers are sticking out everywhere. The dark ones are black and white. the white and grey ones feathers are all growing in pure white. They have slate legs(which is why we thought Langshans instead of Brahma) with white feathers and the dark have orange-yellow legs with black feathers. Any ideas?
