I'm looking to switch over to sand for my coop. Which is best? When I look at Home Depot or Lower I see paver sand, quickcrete.. things like that but no construction sand. Are they the same as construction sand? Also, which sand is better for the birds as far a respiratory issue go? We are currently using a mix of pine shavings and hay. The coop stays a mess and smells. I'm looking for something that is easier to clean up and will help keep the smell down. Open to suggestions Thanks in advance or your help!
