The past couple days 1 of my 6 hens is not acting herself. Definitely possible nothing at all is wrong, but just seeing if there’s anything you all can think of as to why she’s not acting normally. She’s a Plymouth barred rock 8 mos old and is definitely one of the top in the pecking order of my small flock normally. She has been roosting alone and making constant high pitched cooing noises unless she’s pecking around briefly. She walks around not pecking at the ground as much as normal as if she’s lost or looking for something. She’s quiet when I hold her. No outward abnormality to her appearance. She eats treats but I haven’t seen her eat her feed or drink water (I hung out in the run off and on today but obviously not all day). She laid an egg today. No visible signs of mites or lice but I did do a whole flock diametaceous earth treatment. She’s pooping normally. I’m keeping an eye on her for any new changes.
