Good afternoon fellow Chickeners.....We all ready have a 6'x8' coop, that we built about 6 months ago, for the 6 rir that we already have. However, we are planning to get 25 more chicks. So, the plan is to convert the Barn stall, which is 12'x12' ,to a coop for the 6 adults, and provide them with a 25' x 50' pasture run, and put the new chicks in the original coop,until they are big enough to join the adults. I think that will work, but we are still newbees so any advice would be appreciated! Our original coop is working great, and the hens must be happy, we get an average of 40 eggs a week. Thank you.......Don
