One of the three is for sure a doe. One is definitely a buck. The one in question was in the same cage as the buck when i boight them and they got along fine. I separated all three so the does could do there pregnancy in peace. Today i let the buck out to clean the cage hes in( the three of them are in a repurposed chicken coop but separated within the coop) and he and the one im not sure about started fighting right away when he tried to get on.
