She maybe just a late bloomer, I am seeing the same here between Toots and Babe, Toots and Sam started mating when Toots had just turned 4 months old consensual, then nothing from Sam and Babe yet and they are 2 days apart in age. So even though I have had several say Babe is female I won't actually believe till I see mating. You didn't say what the difference in age there is between them.It's been determined here by several people that Moose is a female. She does mount Lucy, usually backwards, but she hasn't laid any eggs. She is not protective and acts like a girl.
