Hey Aurora Springs < I got lucky my brooder started out as Old used double stack baby cribs. the front doors roll up on a track. so we adapted them put solid floors in for plastic trays to sit on and built and painted a wire floor to go over the trays. I only have to lift door about 2 inches to slide trays out. We put in galvinized metal rabbit feeders. I found that the lids for those plastic boxes kittly litter comes in make perfect trays under the lip of the feederd that way food they do scratch out the peck and eat instead of it falling under wire. right now we still have the reg waterers, but are replacing those with nipple waters. I usually use the top brooders with 250 watt lights since heat rises, and the bottoms to transition to either no light or a 60 watt bulb. We built a room in our garage for these to contro;l temp, and so we have a place for incubators too. I have another set of brooders like this in our Pump house/shed. for getting them ready for outside coop, also sometimes use as a broody house out there , or sick pen. then We have 2 grow up pens.
