I have an 8 year old black australorp hen who has a somewhat swollen, firm abdomen. I brought her into the house today to let her sit in warm water. She seemed to enjoy it, but nothing came of it. I felt up her vent and couldn't feel anything. I used a blow dryer to dry her off, and put her back out in the coop, in a crate. I was afraid she wasn't dry enough, so I put a heat lamp on over one end of her crate. She seems to like it. We're in a cold snap for a few days............50's in the day, 40's at night. I think she is comforted by the heat, but am I possibly stimulating her ovaries too much, which might lead to a worsening of whatever is going on? Thanks.
