Oh! And, my "brooder" has become my entire master bathroom...large spa-type tub was easy to disinfect initially and to clean after occupancy and the separate shower stall makes a great storage closet for all things chick related like feed, Apple Cider Vinigar, paper towels, pine shaving bale, etc,
When my chicks got old enough to get out of the tub, I didn't bother putting a screen over it because the linoleum floors are easy to clean and I rather like coming in to find an adolescent chicken or two roosting on the side of the tub or the edge of the vanity
