I have been hassling my husband for weeks to get me a watermelon box for a brooder. He kept saying it wouldn't work, it won't fit, yadda, yadda, yadda. Well yesterday he finally brought me one. I spent all evening cleaning the mess out of my shed the chicks made because I had them in dog cages. I put the watermelon box in, added a perch and viola. No more mess. It is great. I will be cutting out the lid and adding chicken wire tonight so I can keep them in as they get bigger. This is working really well and was free. I highly recommend then. I don't brood chicks that often and so building something was overkill and we wanted to put the time and money into our new coop.
