got home last night and let the girls out to dig. try to pick each of them up once just to do a maintainance check and thank them for the egg of the day. noticed that the Wy had what appeared to be dried egg yolk all over the side of her head...not good, i'm thinkin'. i checked the coop, nests, floor...no sign of anything broken/eaten. i had 3 eggs (4 hens) in the nest. they get plenty of protein, snacks, oyster shell. am i in trouble?
