I'm trying to avoid the run from becoming bare dirt and at the same time provide something for the chickens to eat. I thought about just planting something in there but they would eat the seeds in a day, so I came up with this idea. I"m planning on building some 4' x 8' frames out of 2" x 4"'s and cover it with 1/2" hardware cloth on one side. I'm gonna lay it down in the coop with the wire side up and plant some rye grass seeds or bird seeds inside of it to let it grow up thru the wire and they can eat it thru the wire or just move it once the plants get growing and start over. It wouldn't be much work once it's built and rye grass seeds are cheap and grow fast. I need to know what would be a good fast growing plant/grass/greens that the chickens will like. Has anyone tryed this or something similar?
