I took a dive and ordered chicks from a reputable hatchery. I am picking them up on April 30th. I'm making a coop out of my daughters old little tikes house. The big question I have now is what do I do with the floor of the run? I'll include a picture of where the run is going. It already has a chain link fence around it that we will be adding onto it to make it predator proof. Do I scrape all the grass? Can I just put them in the grass until it gets destroyed? I was wanting to do a sand run/coop for cleanliness. I am going to let them out of the run to free range when I am outside with them. I want to get started right away so that when the chicks come I can enjoy them being little and not worry about their housing.
