congrats!
I usually keep mine in the bator for about a day.. when they get moved to the brooder on day 2 is when I give them the goodies
he won't eat for the first day or two.. the yolk they absorb is really large... however I do offer water to them on day 2 along with some chopped greens (collards, spinach or kale).. they may or may not be interested in it.. by day 3 they should be eating and drinking some
for their water I add something like Save-a-chick or other vitamin diluted down a bit since I give it to them every day and they do drink alot
also sprinkle a little of the chopped greens on the surface of their water (until you see them drinking every day on their own) to entice them to peck at it (you can also tap with your finger.. but the greens on water trick works great)
for their greens.. I use the mix of spinach, collards and kale (collards seems to be a favorite) after a day or two I add in some grated carrots and chopped apple.. but it's still mostly greens
you can also mix layer crumbles into the greens on day 2 or 3... (make sure it's mostly greens though). I have added a sprinkling of game bird starter (for the extra nutrients) plus some chick starter.. but the main crumble is layer crumbles for the calcium and because it's lower in protein
after week one (of greens, layer crumbles and their vitamin water) I switch mine over to a 50/50 mix of layer pellets and rabbit pellets.. their greens & veggie mix becomes more of a treat then
