I have 10- 1 year old chickens...and 10 2 month old chicks. I separated their run, so they could still see each other. sometimes I let them get together...but always end up separating them so no one gets too picked on. The chicks have a wired dog cage with a tarp on it. I have left the door opened with in the secured chicken run...the chicken run that they all share has chicken wire from top to bottom so they are all safe. question is : I just realized they chicks are sleeping outside on some roosts with in the chicken run. Is that ok? I have a armish chicken coop that the older ones just walk in on their own at night. I still don't think it's a good idea to let them sleep together yet. Yet these new ones seem to like to sleep under the stars.....They no longer go into their covered dog/ chick house...what do I do? They have to sleep in that coop come winter, thats for sure. ANy ideas? Is it ok for them to sleep with in their secured run outside all night? They also have a tarp above where they roost at night. Thanks for all your help.
