This is first time it hapopen to me and I haven´t heard of that happening before so I don´t know if is a bug or 1 in a 1000 possibilities that it will happen like in rl. Any way, this is what happen.

I logged in and found two nests in a stump, as i was petting noticed one of my meeroos girls was still in season but the boy she almost always mate with was not, so checked the nests to see who he made with and to my surprise, both nest had the same mother... So now I´m confused... Is that possible?
