My hen has swollen, blistered feet. Her legs are warm to the touch and her feet are red with infection. The pads are swollen and seem to have blisters developing on them.I don't see any scabs indicating bumblefoot. She lays down all the time. We soaked he feet in warm water and Epsom salt, and that broke the blisters, but now they are leaking clear liquid. She is not eating, drinks little. Not sure what treatment method or medication to try. No chicken vets in our area either.
