Today is the first day that my meaties are not outside. And that is only because they are 2 weeks old, and the weather has taken a hard turn from the mid to upper 80s during the day to a whopping high of 52 right now. I have a moveable pen that I use for them during the day, and a 2.5x3.5 dog coop that 10 meaties sleep in. I only just cleaned their coop out for the first time on Wednesday when I didn't work. Also, I move their whole coop and pen once a week. The coop I use is very light. I take off the hinged lid, and I can pick the whole thing up myself, move it, then use the pen to "HERD" the meat birds to the new location. This has worked well so far. SO, at night time they are protected from predators in their coop. I'd like to build a tractor though, and I like the idea of hinged aprons. Only I think, I would lay down a few landscape ties over top of those. They're light enough to pick up and set on top of the tractor while moving from point A to point B...
