Meat bird tractor question.

[Southern Gardener]

I have twenty red broilers that will ship in April. This is the tractor me and my sister will attempt to build this weekend. (the bottom one) My question is how big should I build it for 20 birds? I plan on using a tarp on one end. Any suggestions on building this would be welcomed!

Thanks!

The authors of Chicken Tractor, Andy Lee and Patricia Foreman, suggest a 4' x 10' tractor for 20 broilers.
