Ok..I soaked her foot no black spot.. so if I give her this what is my next step? I should probably give it to the whole flock, right? Then how often to give it to them? I am not sure what else to ask.
I have had a few older chickens recently pass, they both had one foot that swelled looked for the black spot and never found one. Now I have a third one that has a swollen foot, any ideas? I don't have any pictures but can try to get one if that would help. Thank you for any idea you may have.
