i would give her some electrolites, maybe some scrambled eggs- broodiness is hard on them-My broody hen isn't broody anymore, but now she has trouble walking and staying balanced. There are no apparent leg injuries. I looked at her feet, but don't know if they are swollen. She's moving around some, albeit clumsily. I put some antibiotics in their water. BTW, how long can I leave water w/ antibiotics in it out?
