Kuntry girl here is a big

for you!!
I would do as Chicken Canoe suggested and just go deep litter-- stir up the litter every day and addmore bedding and stir again. You can give them grain to dig into the litter but they will need grit also. THe gissard will be more dveloped in the bird that gets grit and grain. I found the litter issue to be the biggest management problem. Holding back feed is not not necesasarily a bad thing as you know-- meaning being without food for a few hours will not kill these pigs.
Constantly emptying out the litter is a PITA. I have gone to DL with all my coops. Easier. I use powdered lime to help with odor, and more shavings ( and dried leaves racked up in the fall). Check out the deep litter thread for info-- otherwise ask Beekissed.
