I let my chickens out to free range about 7 a.m. - then put them up in their "tractor" at dark. This works out great, but I'm going to be gone for 4-5 days next week, and my mom will be coming to feed animals. I was thinking about putting them in my unused 10x10 chainlink, covered dog pen for those days, so my mom doesn't have to put them away at night and come back in the morning to let them out. Do you think that will mess with them too much? Especially in terms of where they lay?
