This morning when I went out to feed the girls I found one of my 14 week old EEs huddled next to the steps to the coop. She didn't get up whenI walked over to her which isn't like them as they are on the skiddest side. I picked her up and she felt cold and she was breathing hard. I brought her into the house and put her in the bathroom with a heat light on her and the bathroom heater on. This was about 10:30. I checked on her off and on and she seemed to be perking up and looking around, but was still breathing hard. A few minutes ago I checked on her and found her dead. Yesterday she was acting normal. I don't know if she some how got left out last night (my DH lets them out before he goes to work) or what. Usually they all go into the coop themselves and I go out and shut the door. Could a night out on the cold wet ground have killed her? It was in the upper 30s last night and we've had rain up until about noon on sunday. Any ideas what could have kill her. Is there something I need to do to keep this from killing the rest of the flock?
