For food, I bought Dumer 20% Chick starter/feeder, can I or should I moisten the dry crumble that I bought for the ducklings? I thought you just give it straight out hard as it comes, but I read in the a previous post to moisten them the 1st 3 days?. I'm setting up my brooder now, I've been getting sung to by the baby! Now their sleeping/heating area, I saw one poster had a box, with a hole cut out at the top so the light shines through keeping the heat in, can I have a box, but with the top open with the light on them with a exit? Or should it be enclosed like the previous poster has for her ducklings? They will have the side of the box walls, and the door way if you will to come/go, but the top will be full exposed to the air. What other things or healthy foods should I add?
