This is the first time I have ever had chickens. I have 9 Leghorn hens and this morning I noticed blood on the back on one of my girls. At closer inspection I saw that she had torn the back of her comb loose a bit and it looks like it is turning pink from that point back. The rest is still vivid red. I am so new at tending chickens I don't know if this is something that will heal itself, or what I need to do. Any help will be very welcome! Thanks.
