Hello - we have 12 chicks coming in the spring. We have one coop already (long story there), but we'd like to build a coop and run for the new birds to live in once out of the brooder since the pre-fab options seem pretty crummy and/or overpriced. Plans are all over the place, and the options in these forums are too overwhelming! We're willing to pay for the plans of course if they fit what we want - I was looking at this one but wanted input if anyone has used these plans or built something similar. We are capable of making some modifications (like adding a couple of top-hinged windows for ventilation along with hardware cloth over them for safety...a predator apron around the whole thing, etc.). They will be able to free-range in a large fenced area so not solely kept in the coop/run except the first couple of days they are moved outside. I recognize we may not end up with 12 but I'm being optimistic - plus having the space for up to 15 would be nice for future additions. Thanks!
