A few months back a hen had injuries to both her flanks, got lethargic and died, despite BluKote & on Antibiotics. At first I thought she got attacked by something wild, but it didn't make sense as they all get locked up at night. Then I saw that her injuries were where the rooster holds on during mounting. Now another hen has the same injury! I'm putting her on antibiotics and spray the area with BluKote, but she is also very lethargic. Do I need to get rid of this rooster? I do like him, so if it's not his fault, I'd rather not. I don't want any more injured hens! Has anyone seen this before?
