Jackie is 1 1/2 year old Easter Eggers. Sunday she seemed off, not running for treats. Looked her over, had an egg membrane partially sticking out of vent. It came out easily. Looks like it had broke from the exterior end. After that she drank and appeared better but not quite back to normal. Monday she was in the nesting box all day and no egg. If I took her out of box she would drink and then go back to nest box. Didn't see her eat. Have abdomen felt normal. Last night she was still in best box after lights out. My thought she was going broody. I put her on the roost. She was out of the nest this morning , and then later I saw her on the monitor she was laying on her side in the coop. (I am at work.) My husband and daughter took her in the house, gave her a warm soak, dried her off, is now in dog crate on heating pad. They did say her vent was pulsing and abdomen soft. No egg visible. Any thoughts?
