Thanks for all the input. I do like that they can be the chickens they are on the dirt floor.
I have some old metal roofing that I could put down a foot or so .......lots of digging. I could buy hardware cloth ........ still, lots of digging. I suppose I could dig a narrow trench and fill it with cement. That is what I am doing in front of the gate to their run. Still, I am tired of digging! I just dug all around their run and haven't even got that trench filled in yet.
I suppose there is no easy way. I am just not as strong as I was when I was younger and don't have as much steam for the big projects. I don't know how I got to be 66 in such a short time......and all the grandkids and great grandkids. Yikes!
Thanks for the help.
