We are building (almost done) our chicken yard and coop. It is 16X16 all together. My coop is 8X8. It is completely caged in with 1 inch chicken wire from the ground up. We have a galvanized roof and we are planning on using tin for the sides of the coop later when we need it for the weather. Right now I think they would rather have the cross breeze. I bought 6 foot 1 inch tomato stakes to make the roosts out of. I ma planning on making 12X12 nests with a slanted roof to keep them from nesting on top of them. We have everything but the roof attached (will take about ten minutes since it is framed out and ready. 1st question... we are planning on using quickrete and digging a shallow trench around the perimeter. We will fill it in about 12 inches from the bottom of the board and wire. Will this be sufficient to keep out critters? I really do not want to go out and see dead chickens everywhere. Right now, much to their displeasure, we are putting them back in their brooder (two month old chickies) at night in the pen. I am hoping that keeps anything from getting them if it digs under during the night. It has 1/4"-1/2" (not sure) wire and top and bottom. It also has rebar as the frame. The wire is VERY stiff. Would have to be super strong to get that puppy apart. 2nd question.. Have we forgotten anything? I have a 30lb feeder to hang from the roof in the coop. I bought a 3 gallon waterer on ebay that hopefully will be here by the end of the week. Right now I am filling the quart jar waterer (total pain in the butt) and feeding them in one of the trough feeders. I am only giving them chick starter and they get bugs out of the yard. Any other advice? As you can tell I am new and nervous and maybe should not have read the predator board. I want Fort Knox. I was going to use a solar electric fence until I priced them .
