Long time reader, first time poster. Just have a kinda puzzling problem (not even sure it is a problem but that's why I'm here, to ask the pros). We got these 2 buffs last March and they are the same age. They were chicks when we brought them home. They both started laying in September and all was fine but I noticed that on one of them, her comb wasn't really growing like the other ones were. Never thought much of it but now we also noticed that her feet are kinda yellow as well. She also never really developed the tall tail feathers like her sister did. She quit laying in November but her sister continues to lay. Poop is normal. Pine shavings in the coop and they mostly free range (when were home, just lost one to a bobcat and are being cautious now). She eats, scratches and drinks just as well as her sisters.
Should we be concerned? The pic shows the 2 side by side.
Thanks in advance.
