So this summer I am ordering between 250 and 300 chickens. 50 to 75 will be layers that I will be keeping in a year round insulated coop but the rest will be my meat birds. My question for the 200 to 225 meat birds is, will it be viable to keep them in a portable coop or chicken tractor. I could build 2 or 3 of them if needed and split them into groups of 50 to 75. Most tractor ideas I have seen are for 10 to 20 chickens at most. My reason for doing this is after starting with 100 chickens this year the grass behind my coop was so over eaten and turned up there is nothing left of it and I love the taste of a grass fed chicken. Anyone have any insite on doing anything like I'm talking about?
