Usually the male is the one to go homosexual, but yes they can.
They will either steal another mates eggs or have a threesome with
a male and then chase him away.
If a boy rabbit has mated with a doe will the doe also mate with him?
I have a neutered male ( Benny) and a female (Millie) living
together and when they are out in a run next to another rabbit the
female (Millie) normally tries to mate with Benny this could be a
dominance thing with other rabbits being around, or even if other
rabbits are not around she might just be a very dominant doe.
