My 3 yr old hen has been limping for many weeks now. Progressively getting worse. I’ve checked her 100 times for all the usuals, bumblefoot, mites, breaks, egg bound, etc. Nothing. The other hens pick on her if she gets too close. The roo sometimes bullies her. I have to either hand feed her or physically take her to the food/ water. Also, have to help her out of the coop or bush most mornings. She still has a voracious appetite. I think she’s still laying eggs. I’ve been catching locusts and worms for her. I don’t know what to do. I gave her half a baby aspirin one day and there was no change.
