My 6 chicks are 7 weeks old and still like to sleep in the pine shavings on top of each other. I know they aren't cold it's been over 70 for the past few nights. Two nights ago I picked them up and placed them on a lower 2x4 I put in there for them only for them to jump down and cuddle back up in the pine straw. They were sleeping in the nesting box but I have since closed it off. Any help would be appreciated. Here's a pic of the inside of my coop
