Hubby, grandsons and son-in-law have started building our coop (mine and SIL . . . oops, actually our chickens' coop ). Did I read somewhere that the roosts need to be flat like a board? What are your roosts made of? Also, when building the run, we must but up to a chain link fence on two sides. We will use poultry wire as hardware cloth is just took expensive in this economy. What can we use on those two sides of the pen (and there are two huge trees with huge roots in the immediate area) to keep predators from digging in? Hubby thought about a small trench with tin down in it and up the side of the run. Please, help us with this. The other two sides, we're gonna dig down and rung wire out to stop digging, I think. But up against the chain link, what can we do?
