Hi! I'm just getting started raising chickens. I'm planning on 6-8 hens. Right now I'm in the 'research' stage. We have a large backyard, so I have plenty of room for either a coop or tractor. I like the fresh grass for the hens with a tractor- but do you find tractors leave brown patches all over the yard? My kids also run all over the yard, and I'm a bit concerned about manure being out in the open where they could step in it. We also have a lot of snow to deal with in the winter, and so I'm wondering if overall a coop with straw/pine shavings, and a run with sand would be a better option than a tractor. What do you experts think? Thanks for the help!
