Has anyone come across a lump like this one please? The chicken is a 1 year old Rhode Island Red, healthy and happy until I saw that someone had been bleeding at night when roosting. Inspected and found this lump. She is eating, laying, and behaving completely normally. I've washed round the wound, and the dirtied feathers with Hibiscrub and put wound dressing powder on it to try and help it scab over. Should I ask the vet to remove it?
