I've repurposed a quail brooder into a chick brooder. It has 1/2x1/2 hardware cloth floor (with metal drip pans beneath.) I'm thinking for the first several days I should cover 1/2 of the floor wire with cardboard, covered with paper towel. This will get them used to pecking at food crumbs and expose them to cocci (am I right about this?). After about a week I would remove the cardboard and paper towel so they would have no choice but to walk on the hardware cloth. I'm hopefull the poop would mostly fall though the 1/2 in spaces until they are 3 to 4 weeks old. Is this a reasonable assumption?
