Might be responding a little late, but we made a ducky brooder by taking a big Rubbermaid tote and carving about a 12' x 18" window out of the lid, then bolting hardware cloth to it (and using large washers to distribute the weight better). I duct taped the edges on the top to hide sharp edges with some of the decorative Duck brand tape. Came out pretty cute, and functional! Our kitten loves to lay on the lid and watch the duck, but since it's bolted it holds her weight fine--heck, I had been prepared for my 2 year old to try to crawl on it. We clipped a light to it through the window for warmth. It was kind of thrown together because we got the duckling by surprise after a neighbor's dog attacked the mom and babies--this is the only one that was left after the mama took off with one and 2 others died.
