I have 6 6 week old chicks. They have a great coop and large run. The run is made of two chain link dog kennels, not sure of size but they have plenty of room. Nice mix of sun and shade under some evergreen trees. My question is: what's the best way to keep the run from being stinky? I am really surprised it already smells. Even when it's very dry and there isn't that much poop in there yet. The coop doesn't smell, just the run. I read some folks mention putting lime down, but they eat a lot from the floor of the pen so I wonder about the advisability of that. Should I put litter in the run? Would love to hear your suggestions.
