I had a doe kindle yesterday. Kits are all fine and doe seemed fine. This morning I took her out of her cage and when I turned her over I noticed that her vulva was very swolen. It is very pale and even looks like a large blister. When push back it opens and look completely normal. I am afraid she go frost bitten. It was -5 when she kindled and the temp has not gotten over 8 since. Any ideas what this may be and how to treat it? I filled her cage with straw so she would not be sitting on the freezing wire but am at a loss for what else to do. Any advise would be appriciated. Thanks.
