So my EE hen Gertrude has not laid an egg in a few days, she also seems more lethargic than the other girls- standing/laying around a lot, going to bed earlier than the rest, and her butt is really poopy- no sign of egg yolk or blood though. I brought her in and gave her a warm bath, cleaned up the poop and massaged her abdomen. I can't feel an egg in there, but her abdomen does look swollen. I don't have any experience feeling for an egg so there may be one and I just am not feeling it. She doesn't seem to be uncomfortable- she is eating and drinking normally, but I am worried about her. She is in a box inside tonight, hopefully she will be feeling better soon. Any advice on what else I should do?
