I have a 10x20 dog kennel run with a 4x6 coop inside the run. It was used for my hens but they are moved to a new and bigger coop and run. So now that I have the free space I was thinking of getting 25 Jumbo Cornish X Rocks from McMurray. I would brood them in the coop until they feather out. Will they need a coop for night time or will they fair okay outside in their protected run. I understand they will be processed at round 6-10 weeks old. Here is a picture of the run and coop. Let me know what you think please.
