How often do I need to change the substrate for my baby chickens?
I have put down 3" of horse pellet type bedding substrate which was recommended to me by the grain store where I ordered my chickens. It is thick and although there is a lot of poop in there it drys quickly and the five chicks I have left (one died today) have plenty of room. They are now 11 or 12 days old and are in a 40 gallon fish tank with a mesh top and a heater. Everything looks nice and dry and I clean the water and feed containers daily and clean out any poop I see. The bedding is expensive and I put half of a 25 pound bag in there to start. My husband says that it doesn't need to be changed but I'm afraid it made my chick sick. The chick was perfectly fine last night and was dead less than 24 hours later with bloody poop. We isolated her immediately. How often should I change the bedding?
