Hi all! We have had layers for over a year and want to do a bunch Of meaties before winter. I have read a lot of the info here And it is wonderful! Very detailed and easy to understand. I am a city girl by background and I dont understand the concept of a chicken tractor. We plan on doing about 50 meaties. I want to ensure at least 3 sq ft per chicken, or more if you guys think so. I don't want my meat birds To be miserable. My chicken tractor would have to be at least 10 by 5 in that case, plus the covered area. This is going to be heavy. We actually have a real tractor that we can use to pull the chicken tractor around the pasture. How do we make sure the chickens don't get hurt when we move it?
