We got 8, RTL hens on saturday, They're supposed to starting laying here within a couple weeks, however they refuse to go outside in their run. We made a coop out of an old area in our barn, its about 7x7 inside the barn, then we made a run outside the barn about 8x10, however the birds just hang out in the corner of the coop for most of the day, is this normal? Any help to get them to go in and out of the coop and run?
