Here's the story! I ordered 10 EE, 5 BR, and 5 NN's and received them from the hatchery on May 8th, so they are almost 4 months old. I have a 3 tiered roost, with each tier one foot high and one foot away from the one below it (which makes the top tier about a foot from the wall and the bottom tier about three foot away from the wall). It's made from 2x4 with the flat side up and the lowest tier is about 4 foot off the ground running up to 6 foot high with the highest tier, and the ceiling of my coop is 2 foot above that. The chickens will also get on the roost during the day but at night they all lay in the shavings on the ground and pile up on top of each other even though the coop temp. has been 100 degrees during this hot summer. The roost is also beside a screened window so if there is any air moving (which there hasn't been) the chickens would have the benifit of that breeze. We have tried put them up on the roost during the night but they just walk around until they fall off! We have tried everything I know of to get them to stay up there during the night with no luck, what am I doing wrong?
