Six months ago I bought 2 baby does and a baby buck. They lived together in one of my aviaries which contained a couple of open hutches and assorted junk for them to play with. About two months ago I noticed the Buck trying to have sex with the brown doe, The next day I found him dead. So I now had a white and a brown doe, A week ago I found that the brown doe had made a nest with hay and fur in one of the hutches. I then noticed that the white doe tried to mount the brown doe. We caught the white one and found that it was a Buck. So we removed him and put him in his own aviary. We examined the brown doe and she does not appear to be pregnant. But what about the nest she built.?
