OK so i have 3 mallards. 2 females to 1 male also and older khaki hen. The mallards are about 10-11 months old. They havent laid eggs yet. I have seen the drake mate both of them. So my question is when can i expect fertile eggs. or their first eggs for that matter. Oh and will the drake mate with my khaki hen also? Thanks in advance for any and everyone that answers !!!
