i have 8 hens and a rooster all about 8 months old and doing great. i live in a temperate climate in california and it rarely gets below freezing at night these days. yesterday, i noticed one of my hens didn't jump down from the roosting bar when i let them out of the coop in the morning. this morning, she didn't get down but i noticed she is acting different. her eyes were half closed and she was kinda "hunkered down". i took hr down off the roosting bar and she was not interested in the morning ration of scratch. she is just hanging around inside the coop not doing much. i noticed when she breathes, it sounds labored or almost as if she is wheezing. her eyes are half closed and sometimes all the way closed. she is not herself. i haven't seen her eat or drink this morning. any thoughts or suggestions? worried. i'm new to my chickens and this is my first flock.
