I built a brooder last month and it works well. Currently the bottom is wood and I line it with a vinyl table cloth. This system works but I keep this brood inside my house which generates issues such as bad smell and dust from the woodchips. I would like to use ½x½ hardware cloth to line the floor with then below that add a piece of plexiglass. That way the plexiglass can be taken out and hosed off every couple of days. No dust, no smell. I keep the hatched chicks in a plastic bin, lined with paper, for a week then transfer them to that brooder. My question is for standard sized breeds what age can I put them on a hardware cloth floor? Also, does anyone foresee any other issues in construction or animal health to changing to this type of floor for my brooder?
