I have a hen that has a odd bit of growth near hear tail and she has been breathing heavily, swatting down, and she will not eat or drink. She spends all day in her nesting box? She has been like this for 2 days and I am starting to get worried! Today I noticed that it looks like there might be an egg that will not come out. Is this because of the hot weather? Is there anything I can/should do? will she survive? Any advice? Please help!
