You could always call your vet and ask what a visit would cost, it varies I'm sure from state to state and vet to vet. Try what Haunted says first using the warm ES soaks and painting with the iodine. I am treating a chicken hen for a small bumble with iodine right now and it is looking good. I wait till she goes to roost pick her up and put the iodine on her, then blow to get it to dry before putting her back on the roost. When you rub your finger across this swelling on her pad do you feel anything? hard place in the middle or roughness?I hope too! How much would it cost to take her to a vet and have her treated do you think?
