I have an 8-week old pullet who was hurt by a dog. We thought we had her all patched up, she is walking well, eating, drinking, roosting with others at night. BUT, now she has started this strange behavior of pecking in the direction of food but not hitting it. She pecks at the air. When I go up to check on her or to shut the chickens up at night, she is laying in the food bowel. She seems to be able to see, follows me, etc. Anyone seen this before??
