we originally had three big girlies , then at one point added two who were younger, one of them died when a predator got it, and then the remaining wyandotte was found two weeks later flipped onto her back dead. i had a similar reoccurence today. my three big girls who are all about a year old are still around, they are an amerecauna, barred rock and a rhode island red. we also have one girl we just started laying, she is an amerecauna who is very shy. we also have three girls who are about 3 and a half months old. a black jersey giant, barnevelder, and a speckled sussex. they all seemed to be doing well until yesterday. i went down to the coop and my beautifu jersey giant was laying oddly on the ground beneath their water container. her wings were drooping and she is usually quite the active chicken already larger and more authorotative then her elders. i brought her up into the chicken much to the distaste of my dogs and cats who had to be put in their kennes. i laid her (roxy is her name) on a towel and put a bowl of water in front of her. i got her to drink some and then tried to get her to eat. she even denied her favorite table scraps! she seemed like she wanted to sleep so i wrapped her up in a towel and let her be for a little while. after a while i got her to drink more water then i put in back in the coop up away from the other girls who would have pecked at her. i put her in a litter box filled with bedding to make it comfortable. it was warm inside the coop but not too hot and i offered her more food. it was getting late so i left. when i went back in the morning the first thing i saw was that she was drooped over the sides of the box, wings splayed and head dropped dead. what has caused this? any ideas? she seemed find up till yesterday except from a very small bald spot at the base of her neck . i have six chickens who still need to be cared for any no clue. i panicked when i saw her and ran from the coop, i know i should take her out but im slightly afraid. what is this? how can i prevent my other girlies from getting whatever it was? thanks for the help!
