What kind of sand? We are using washed yellow construction sand. We've had 3 chickens die with respiratory problems and wondered if it has something to do with the sand. We are still using it but we're adding more ventilation to see if it makes any difference. I agree about how easy it is for cleaning.
I wanted to use sand in my coop but double check with a an avian vet in my local area m, and he said he would ABSOLUTLY NOT use sand and that is WILL give your chickens respiratory problems or could cause them to die.
