Sleeping in nest boxes?

Your coop look very nice.

I am not sure if it is the angle, but do you have enough space on your roosts for the chickens to sit?

Also, they are probably looking for warmth in the nesting boxes if it is that cold. In the winter I put straw in the coop and mine bed down in the straw for warmth. Straw is warmer than shaving although it is a little harder to clean.

 

Give them several nights to adjust first. When I first moved my girls into their new digs, they all crammed into a nest box too. I think they are very much creatures of habit and change really rocks their world. They are probably a little scard and to huddle together makes them feel safe.

I didn't do anything and after about 4 or 5 nights, they figured it out on their own and were all up on the roosting bar and have been ever since.

You could put a ladder up to the lower roosting bar or an upside down bucket to make jumping up there a tad more easy. That might entise them. But I'm pretty sure they will do it on their own. Roosting is what comes natural to them.

 

It could be due to the temps, but you seem to have some hardy breeds. Is there anything covering the coop other than the hardware cloth?

I would try to put them on the roost after dark. I did have some bantams that would sleep in a pile, but as soon as I got some others that roosted they followed suit.

 

What kind of roof do you have? That looks like it could be open? I've seen chickens roost in trees outside when the temperature was in the single digits fahrenheit, but that was in a very protected valley. I'm probably looking at it wrong, but if it is open, the roosts may be in a draft.

Assuming I am looking at it wrong, which I probably am, try not giving them enough light to get to the nest boxes when you move them inside if you can. Use a small flashlight with the light covered as much as you can, and set them directly on the roosts. They may learn on their own in a few days, but this might speed up the process.

Another idea, keep them locked in the coop a little before bedtime. Get them used to going to bed inside rather than using the roost in your run. I'd go so far as to take down the roost in the run so they don't have that option.

Good luck! Behavior modification can work but it is not always as easy as we like.

 

You can put one on the roost after dark and see what happens the next night. You might want to try this several times with different hens. You might even stick a treat up there.

 

Mine did that at first, too. For a few nights I removed them and covered the boxes so they couldn't go back in. They found the roosts on their own and haven't been back to the boxes except to lay. I think it was 3 or 4 nights.
