Hi, y'all. My rooster has given in and now says his chick can have chickens in a coop. Our best place, I think, to build the coop and run is an old dog kennel (has concrete floor with chain link embedded into it which would keep critters from digging in. Questions . . . Do I need to build a large layer of dirt/sand onto the concrete to help with the chicks' legs? Oh, we're gonna build the coop inside the kennel. A friend is giving me two grown chicks and two babies and a baby rooster. We won't be able to afford some of the fancy coops I've seen on here (wish we could 'cause they are so cute!). The kennel is about 8 ft. wide and about 12-15 ft. long. We're gonna cut a hole in the side of the fence to give the chicks a way out of the house for the day, and have a covered run that will be about 15x20. What's the best and easiest way (under old trees with big roots there) to make the run inacessible to digging mean critters who would hurt our chicks? Please, any and all suggestions and ideas . . . Our chicks thank you and so do we!
