I have a 15 month old barred rock hen. She has been sitting on an empty nest with one golf ball in it for 2-3 days. She sleeps in the nest and does not get on the roost with the other chickens. She makes rocking motions at times and other times she just sits listless. It has been 90 plus here in GA during the day and we have not seen her go get any water. I felt around under her for a possible stuck egg but not sure what I am looking for. Today she looks very weak and not holding her head up. I pushed her off the nest yesterday and she pecked around a bit but then got back on the nest 20 minutes later. I'm worried about the lack of water.
