i am new to the chicken 'business'. i get my pullets in about 6 weeks (10 of them). i am just raising in my 3 1/3 acres in indiana. i am building a chicken tractor (with the help of my father-in-law). i was wondering about predators entering from the bottom. i am putting welded wire all around and at the bottom will be 2/6 boards. since the coop will be on wheels and i need to accomadate for the little space between the wheels and ground (an uneven ground) i was thinking about putting the wire sloped out at the bottom because i cannot bury it into the ground. any thoughts???? on any other good ideas/suggestions!
