Hello from winter white MN. Help, I'm wanting to clean out the coop but my composters are both full and FROZEN. What could I do with the litter? It's about 4 inches deep and I toss it every day but there seems to be more poo then litter these days. I don't want it to get any deeper as then it gets into the feeder my hubby made. Could I store it in black garbage bags until spring?
