Hello everyone! I'm a first time poster but, as they say, a long time lurker who has benefited from all the fantastic information provided on this website. Thanks to all! My issue this morning concerns two of my three Golden Comet hens, my only little brood, refusing to return to their roosts at sundown (I own a Catawba Coop style ark). The other, the alpha hen, leaves the run and returns to roost without fail each and every evening. Until three days ago the other two hens followed the same pattern and had followed it for several weeks (I purchased the hens in April). Even when coaxing them into their roosts the last few evenings these two hens refuse to cooperate, jumping back down from the ramp, preferring instead to remain on the ground. Does anyone have any suggestions? Is it the heat perhaps? Thanks in advance! Update: all of them slept on the ground last night including Leader One. Puzzling.
