Hokay, I have a great water heater in the smallish coop, lots of hay on the raised wooden floor, lotsa pine shavings on the roosts--but after I added a light, they won't go in at night. The bulb holder had a warning: Made in China and wash your hands after handling as the lead will cause birth defects. Christmas night was going down to 6 degrees, so I thot to risk the lead until I can try and find something else, altho they all seem to be that same silver finish that is so toxic! My old, non-toxic one died awhile back. So tonight, they kept piling out of the coop--into the freezing dark--very odd. Then, when I got them to go back in, the rooster faced the wall and kept crowing. He often crows facing the coop walls. What? I know he crows when folks visit, and for general communication, but... Earlier today, gathered some new eggs and the hen who laid them went back and sounded like she was crying, she was so upset they were gone. She still seems in shock, just stares into space. Is this emotional trauma or the lead paint? Otherwise, everything is fine. Are you sure they weren't brain-damaged being at 95 degrees for weeks on end as baby chicks? My other hens could let themselves out of the coop in the mornings with a little push, these wait for me to open their door.
