The first time we got chicks was pre Y2K. We built a huge chicken house, and bought 250 BOs. They free ranged all over the ranch for a while, then we built them a big yard.
After about three years we got rid of them, and dh didn't want anymore. A friend had to move and I ended up caring for her hens at her farm, got tired of going there every day and brought them home.
Now I have 14 at our farmhouse down the road, RIRs, California Whites and Silver Laced Wyandottes. They will stay there, but can't free range because of a neighbor's little dog. Definite chicken killer.
I also have some banties in various stages, some at the farmhouse and some here at our house, and two guineas that were raised with the banties. When my babies are big enough all the banties are coming home.
When I bought the big chicks we did not have a renter in the farmhouse, and didn't know about the neighbor's dog. Now with the dog and the renters it doesn't look like such a good idea to have chickens there. I don't mind going over every day because it's just a mile, but I hate bothering the renters by walking through their yard everyday to get to the chicken house. But I don't want that many chickens here at my house either, my garden suffers.
