Why? Why would they be doing this? I have nice 2x4 roosts (flat side up!) with room for everybody. The hens are almost 2 years old and they used to sleep on perches (some of which were much less comfy in our old coop) but now all 3 of my Columbians sleep in the nest boxes every night. There are 8 nests, so if they would all lay in DIFFERENT boxes than the ones they fill with poo I wouldn't care. But they never do. All their eggs are in poo-filled boxes. I work the whole day, I cannot possibly clean them out except on weekends. All my eggs are filthy. Stupid Columbians. Everyone else is good. The gold laced, the sliver penciled, the Blue lace reds, my BR, BOs... Everyone. Including the pullets who may not even be laying yet. What can I do? This all started, I think, after a dog attack. My roo was injured badly (1/3 of his feathers and 1/4 of his skin gone, plus some damage to his leg that caused a limp for a few weeks) But the tough guy wouldn't tolerate being put in the sick ward. He was bound to re-injure himself trying to escape if I tried isolating him, so I let him back out with the girls so he'd calm down. He slept in a nest box (one of the ground floor ones) until his leg healed. When he started sleeping in a box, half the flock followed him. Most gave it up when he was back up on the top roost like his normal self. But those darned columbian wyandottes... most uncooperative chickens ever. Any suggestions? Would physically putting them on the perches each night for a week or so get them to do it on their own? Or are they just hopelessly stupid?
