Ok, I know this sounds dumb, but... I have two Pekins they are a year old. I was pretty sure they were both male, they both have a curved feather... So, for about the last 2 weeks or so one of the seems to be trying to mate with the other one. They wrestle around in the pool, and he bites onto the others back feathers, etc. I have been on the lookout for eggs, should be easy since they are in a pen, but nothing. I would not care except if the are both males will one end up killing the other? Like a dominance thing? They are the only thing in the pen, just my 2 ducks. Any ideas?
