I just added a golf ball last night and they just rustle around in there so much it ends up buried. Right now the egg box has shredded paper and the rest of the coop has pine shavings. I have had it all pine shavings and that didn't seem to make a difference. I know that they do go onto the roost at times, but it just seems they like to play in the egg box. I could try to put a piece of cardboard or something in there, but I think that the buff orpington that I put up in my first head induced pictures is getting close to laying. The thing is I am worried it has become habit and it will be hard to break because they have been doing this for weeks. I could kind of understand it when we first put them out it was getting chilly, but now it has been getting into the 90s and they still go up there and do it even during the day at times.
I guess if all else fails it will be an egg hunt in the coop, it is small enough but that would require me to take a side off as opposed to opening an egg door. If I seal off the egg boxes for a while how long do you suggest I do this?
