I have 1 Peking drake (Ping), who has 3 female ducks with him (1 Peking, 1 Rouan, and 1 Indian Runner). I just got them this spring, and Ping has just recently (within the past week), started trying to mount the ladies (all 3). Up until today, everything has seemed to be ok, Quackers (Peking), and Josie (Rouan) follow Ping around like he's the king, and Twiggy (IR) mostly does her own thing. This morning though, I went out to check on everyone (They free range in a large fenced in area with my chickens), and Twiggy the IR had feathers missing and blood on her back/wing. I cleaned her up as best as I could, applied triple antibiotic, and used a gauze strip to wrap her wing/back area. I also cobbled together a "bachelor" pen, into which I put Ping.
So I guess my questions are: is there anything else I can/should do for Twiggy? She's acting normal, but I don't want to miss something that would help her.
Could something else have caused Twiggy's injuries? (I know we have a couple of small kittens that live in the barn next door, and I have caught them in the chicken yard, but they are still very little)
Is this normal mating behavior for a young male Peking? (and will he grow out of it/calm down?)
