With chicks, I put some dry down on the paper towels or a shallow cardboard box top, or what ever the first day, as I think it supports their natural tendency to be picking at little tidbits they find on the ground. I also give them a plop of FF. Be sure to make it very small. They will play around in it, and eat some. When they are eating well, I take away the crumble on the floor and give them just their FF. Depending on how many chicks, I either put it in a shallow dish, or just plop it on a lid, or a piece of cardboard. When the first plop is gone, I give them more. I don't like chicks to go without food, but, if you're using the heating pad system, they will not eat at night in the dark. The important thing is to keep the container appropriately sized to the chicks. If it's soupy, it would be possible for them to fall in and get trampled. Dry is better!
