Ok so while looking for a material to use as "bedding" for our chicken run that needs to be ready in 4 weeks (I have 5 two week old chicks. Never had chickens before), I was considering sand but I would need a ton of 60lbs bags. 50 bags to be exact. That's over $300 and I'm on kind of a tight budget. Is there another material that would be cheaper but good for the chickens? I live in Indiana (to give an idea of the climate) and the run will have a roof. Sand seemed like a good option but it's more expensive than expected.
