We had one chicken of our 3 that was egg bound. We took her to the vets and she juuuust made it, they were going to pull the pin 15 minutes later. Anyhow, it's been 2 weeks since then and one day we had 3 eggs! So assumed all is good. The past two nights, the same chicken has been sleeping at least one hour before the rest of them go to bed. She poops normal and we checked her butt, it's not pulsating. Tail is up. What could be wrong you think? She seem lethargic..
