Luna, my 9 month old Easter egger, was acting strangely when I went to feed the girls this morning. At first I thought she was laying in one if the nesting boxes, but when I peeked in she had her eyes closed and was very still. I watched her for several minutes and she still had her eyes closed so I took her out of the box and brought her in the house. Her pulse was rapid ( not sure how fast chickens heart rate is) and her breathing really shallow, her feet felt cold.( I kept her warm) I checked her vent. No blood but she did have white stool around her vent on the feathers. Her eyes looked clear the few times she opened them. I tried to give her a little water( not knowing the last time she had any) but when I tried to tip her head up to dribble a little into her beak she put up an weak fight. Her neck feathers were really puffed up. She wouldn't/ couldnt stand. She couldn't hold her neck up. Sadly she passed away within an hour. The thing I did notice was a weird smell. Usually She smells like pine shavings and layer mash you know, those good chicken smells. Luna had this smell... Hard to describe.... Almost like that sick smell we humans have when we've been throwing up and have been having diarrhea. Only this was a sickly yucky chicken smell. I know that she has passed but I'm worried about my other 11 chickens. Any ideas on what she might have died from? Do I try and sanitize my coop in case of infection? It's 16 degrees here today should I remove the chickens from the coop to my basement? Any medications I should have on hand just in case? What should I with her body? I put it in a cardboard box outside for now. I'd rather burn it than bring her to the dump. Thank you for you help in advance.
