Hello Chicken-friends! I've been lurking for some time now, reading and learning, waiting for the opportunity to raise my own chickens. And its here! Well, in the building stages, anyway. I've wanted chickens for years, and now we (my very patient husband and I) are in the planning stages of my very own chicken house (chicken tractor, actually, long story). The base structure is going to be a re-purposed boat trailer, the resulting structure 8x10, with pasturing below. My concern is this: I would like larger birds, however, the 4 crossbars (3" wide) on the trailer are 16 inches from the ground. The actual floor will be closer to 26 inches from the ground, allowing for quite a bit more head space. So, suggestions, recommendations on breed types that would be amenable to this type of environment? I'm in southwestern pa, closer to the mountains (I can see it snowing on the ridges today), but with mostly open acreage (the wind blows). I'm planning on six hens, no chicken math, and would like eggs, but they don't need to be prolific layers. Thank you all ahead of time or your thoughts and experience!
