This morning Lumpy was acting normal. About1:30 pm she was laying on the coop floor. She got up when I came in, but I scooped her up anyways. I could tell something was off. She wasn't fluffed up but seemed tired. I checked her vent and it was normal. Felt her abdomen and it was normal. Checked for mites and there were none. Felt her crop... empty. I brought her in and crated her. Gave scrambled egg, cup of feed and water. We had to leave for my son's play. We got home at 11pm and she was dead. As I was taking her outside I noticed that her vent was now absolutely NOT normal. What is this? How could it happen so quick? I will add that Lumpy is 10 months old. She is named Lumpy because she had severe way tail. But has never had a problem laying. I'm not sure when she layed last as I am dealing with an annoying and unidentified egg Eater too. Does anyone have any idea what went wrong? The rest of the flock is fine.
