OK, the nest boxes are up 18-24" up from floor, hen is sitting on eggs. Eggs hatch, baby peep fluffs under/next to mom (?), now its time to go and find some food. Fall out of nest(?), feed, drink, scratch, hello world. Now its dark, mom is back up there. How does the chick get back to nest? Or does it? Is this when brooders kick in? aren't the mom hens the brooders? does one set up a box lower or on the floor for both? I'm beginnig to visualize a series of mini ladders and stairs in an Escher-like maze... I can't find the book that spells this out for me...advice please?
