Okay quail folks--I hatched 7 buttons nearly a month ago and they are cute as can be, but OMG do they smell! I*ve had them in a 10 gallon tank and a medium bird cage (both are too small for 7 grown birds, I know, but I*m using them for brooders) with about 3 inches of wood chip bedding and after only a couple of days the whole room stinks. I was planning on keeping two pairs--one in the aquarium and the other in a cage. How often will I be changing bedding?
