I always hear talk of people keeping their new chicks in the coop for a few days to a few weeks to become familiar with it and associate it as their home. I assume this is so they will put themselves away at night. Anyway, I did not have any worries about this with my flock that is now 17 weeks because it was still cold outside when I moved them from the brooder. However, the batch I have now will be six weeks old when I move them in a few days. My worry is that it is going to be in the 90s all of this week and I just don't want to lock them in a box when it is that hot outside. There is ample ventilation but there is in their brooder in the garage as well and on really hot days the chicks will start to pant so I move them to a shaded area in a temporary play pen made of hardware cloth (they are thankful for that). Anyway, my run is attached and enclosed so aside from the possibility that I will have to catch them or chase them and put them in their coop at night for a few days is their any reason to keep them locked up in the coop? (As for free ranging, that will wait a few more weeks as I have another flock that is oh say 500 yards off and if I let both out and the older flock picks on them I think they are still too small to defend themselves.) Thanks in advance.
