GQF Manufacturing Grow Off & Holding Pen 0701
Product Review (submitted on September 20, 2013):
This is the exact same box as the brooder, it just doesn't have the heater installed. I am using a heat lamp ($10) instead of the $140 heating coils. They're just not needed unless you're keeping this in a barn.
For quail (like I'm using) there's plenty of room for 50 even though it says 100 can fit. You loose room because for quail you can't use the outside feeders and waterers, you have to use floor space for inverted chick feeders/water. Cleaning is a breeze, I used the included mat until I switched to the wire.
I recommend replacing the dropping tray with the rabbit cage plastic tray, it slides in perfect and is deeper and lighter. That way you don't need to clean tray but every couple days.
