Both of my chickens have chicken pox. One barely has any warts/bumps on it's comb or eye area. The other has such bad pox that she can no longer see out of either eye. Due to the lack of eye sight, this morning she is no longer eating or drinking. We all know what that means. Is there anything I can do to help relieve the pain or swelling in her eye area? I thought about Neosporin... is it safe for chickens? Thanks for any advice.
