This is our 5th year raising broilers and we're changing it up! We're raising 30 Cornish Xs again and this year we will have them in bottomless tractors as opposed to screened-bottom tractors. We purchased a movable electric fence to ward off predators. The tractors are only 2' high instead of 4, and since they are bottomless, we can pick them up to move them, so no wheels. They measure 2x4x8' and we have two of them. We have a tarp canopy to go over them for shade/rain protection. We're hoping for even healthier birds since they'll be on grass and won't be on mesh (or mess since the mesh caught all their droppings!) The birds arrived yesterday and we already have them on nipple waterers! No messy waterers to deal with. I tried our mini feeders (1.5" street elbows in plastic quart canisters) , but the birds are too small and could hop into them, so they are on traditional feeders for now. They'll be on the new feeders soon enough. We process the last weekend in June, which is 2 weeks earlier than we usually do it - we're going for smaller, tenderer birds. Happy Broiler Raising everyone!!
