I am starting a new system for my chickens this Spring, and I haven't been able to find much useful info on space requirements for chicken tractors. Can anyone help? Here's the situation: I raise pullets until they are 2.5 months. I've always kept them in a regular coop + yard, but this year I'll be doing some 200, so it won't be practical. I also have a big field I would like to turn into good pasture. So, I've decided to build totally enclosed (half covered with tarp or metal roof, and half with hardware cloth) pasture pens that would be moved daily. What is the minimum space each pullet would need in the pen to be comfortable? They would have new forage every day, and wouldn't be in the pen after they were 2-3 months old. My other question: is it a good idea to use chickens to till land so that I can replant in the fall? I don't want them standing around in mud for too long, but I would like to use them to break sod, if possible. Thank you so much! I know it will be a lot of trial and error, but it's been a fun process so far!
