I've been using Dumor nonmedicated starter/grower, grower/finisher and now layer. I'm getting fine results (chickens are also on range/pasture and have extra shell available). However, the TSC stores are about half an hour away and a great local mill is very close, so I'm trying to put together...
Have you worked out the square footage yet? I am thinking about using their large complex plan. Which one are you modifying?
Please keep us posted on how it goes!
