My husband and I are in the planning stages of our tractor coop for four chickens (an Ameraucana, a Silver Laced Wyandotte, and two Cochins) which will arrive in April (I know the flock will be expanding, inevitable right?). The tractor will be 5'x12' with 5'x4' of it being the actual coop area and the rest is the run. The nest boxes we're planning will be four 12"x12" nests (not too small I hope..?). So my question is; what are the pros and cons of making a nest box that is on the outside, with the traditional "roof-lid" design, and what are the pros and cons of the nest boxes being completely inside the coop, with the nest door being flush with the exterior wall? I'm at a loss on which design we should pick , please help! Sorry for the long winded question, I wanted to provide enough info for good answers . I'm adding a poll to this for easy answering, but I'd love to hear your explanations on why you chose that answer. Thank you so much for your help!!!
