I have newly hatched floofs on puppy pads as well right now and am planning to switch them to pine at 1 week then mix hemp and pine for a little bit. It feel like that works well too
eventually I’ll merge the 2 week olds and hatchlings. 😬
I changed from pine savings to hemp at 1 week. They did eat the fibers and their crops got big and hard, but I provided some starter grit in their crumble and it helped them process it. Now they don’t eat it as much since they are used to it.
