I went on vacation for 4 days and when I came back my neighbor said his dog attacked one of my chickens. All but one of her tail feathers were ripped out and she seems to have a gash on her rump area. I brought her inside and washed the area and put neosporin on it. I need to know if I should put her on antibiotics or if there is something else I should do. The area is tender to the touch. She pulled away when I touched it to clean. She is eating, drinking and pooping fine. I kept her inside the first night but last night I let her back inthe coop. Any suggestions? I can post pics when I get home if needed. Im a first time chicken owner and my girls are like pets. I'll do whatever I can!!!
