So today is day 21 and lock down is approaching my little duckling is doing great and is in position with his head under his wings the egg is getting heavier and all looks well. I want to put together my brooder box anyone have any good ideas for this? Can I use a large Rubbermaid tub? Can I use a regular light bulb as I did for incubation? What temp should it be to keep my duckling warm? And advise as in how to do this? And how long do I have to keep the duckling in there?
