My 9 month old hen was bitten by a dog. The wound is about an inch long and maybe 1/8 of an inch deep (and she's missing a bunch of feathers from her rear). The following day she was not moving around well so I brought her inside the house and now have her in a dog kennel/cage with a towel to sit on (water and food). She's able to come out of the cage and wonder around throughout the day (she's becoming a spoiled house pet). I've been cleaning the wound a few times a day with peroxide and she doesn't really mind. She's doing MUCH better and she is acting perfectly normal and energetic - when she's out of the kennel she follows me everywhere. *** But, over the past couple of days, a small black / greenish area has formed next to the wound. It does not smell unusual, it's not warmer than the rest of her skin. It may be just bruising, however, I'm not sure. I put a tiny bit of triple antibiotic plus ointment on the wound today for the first time. Is it normal for a black / greenish spot to form? Should I be doing anything else?
