I have 3 ducks that I got late this spring. Ive been questioning the sex of them...been waiting for the tell tail curled tail; but hadn't seen anything to indicate male or female. My husband and I have both seen one of the ducks mounting the others, so we assumed it was male, however they've just started laying (this last week) and I'm pretty sure that Im getting 3 duck eggs a day. (hard to be 100% because we also have chickens that have been laying in the duck nest). Is it common for a female to mount other females? We've only seen it a couple of times, and theres been no other remarkable behavior amongst them. I'd appreciate any "expertise" info from you other duck lovers! thanks!
