I have a question that I really would like to have an answer to. This morning I picked up 4 new female ducks. I got home at 8 am and by noon, one of the poor ducks had no feathers left on the back of her head and neck. She was actually bleeding all along the back of her neck. So I put her alone in a pen to get the drakes away from her. But she is the only one they would just not leave alone. The drakes all wanted to mate with her and one after the other I guess they did. All 3 other females are mature and 1 year old. None of the new females were giving any signs like head bobbing. Why did all the drakes focus only on that one poor duck? Is there some kind of scent a female has during a time or something like that, which attracts all the males? Thank you for any info on this.
