We have 3 lovely chickens but over the past month or so, our white chicken, Baby, has started to peck our black chicken, Granola, whenever they eat from the same spot. It only happens maybe once a day or once every other day, so we thought maybe Baby was just establishing dominance or being a bit protective of her food. However yesterday we gave the chickens some corn on the cob, and Baby pecked Granola's comb, and it started bleeding a little. Granola was a little shaken, and since the injury was so small (like a pin prick) we thought we'd let her sleep it off. The thing is, Granola woke up this morning a lot more quiet and reserved than she usually is, and she's fluffing herself up and closing one eye. Right now, the other two chickens are digging, but Granola is sitting on the floor and opening and closing her beak a little, as if she's mumbling but not making any noise. Do you think Granola's shy behavior is a result of yesterday's incident, or could she be ill? How do we stop Baby from pecking Granola - Baby ONLY ever pecks Granola, and none of the other 2 chickens peck each other at all?
