Hi, I noticed one of my hens spending a lot of time in the nest box recently. I thought she was just going broody, because she was still very interested in food. This morning I notice she was very listless, and when I picked her up it felt like she was very bloated. Now she's just standing in place, in the pinguin stance. I'm afraid she's egg bound or something like that. Any suggestions for anything that can be done for her?
