I have a barred rock hen who has been acting off for close to week. Her comb is pale and she’s been acting slightly lethargic. I think she was still laying earlier this week but I haven’t been able to tell the past few. Tonight as the we’re settling down on the roost she seem to be trying to hide under one of my roosters she was chirping almost like a chick and trying to hide under him and grooming him, picking dirt off his feet and picking stuff out of his back feathers. This is odd in and of it self none of my flock groom each other! Any idea what’s going on? It was warm earlier this week but it’s been cold the last 2 nights could she be cold?
