I finished the coop and the run... ok... my husband did, but that's beside the point and now I am standing back, looking at a patch of dirt. I didn't want to put it on grass because I know they will just ruin it anyways, and we had a bare level area that was just dirt. So now what do I put in the chicken run? I still have the bedding that I used for their brooder- a big bag actually. But they seem to like scratching and digging around in the dirt. I am just concerned with the rain- living in washington and all. Tonight will be the first night the peepers are out of the house. They are 4 weeks old now... should I put out their heater for them? It gets down to mid 50s-60s at night. There are 6 of them, will they huddle and keep warm? Thanks!!
