My favorite chicken got attacked and has a 2x3 inch hole in her back. She seems to be doing a lot better today and to my surprise just layed an egg 5 minutes ago!!! I have been feeding her eggs and honey water. OK Question: I have heard that she needs antibiotics. I was going to take her to the vet tomorrow and get some from them, but that is $70 cheapest. Can I just use antibiotics from the feed store? Are those the same antibiotics that she needs right now? Are the vet's antibiotics better?
