Also, start giving your 5 week plus chicks some grit, in the form of small rocks, like rose quartz that is in the bag of chicken grit that I buy (hopefully smaller grit for the chicks). That helps them grind their food and the bugs, grass, weeds that you give to them! I'm training my girls now to peck my hand, and not my fingers, by putting a little water in their food, making a mash ball on my hand and holding it flat. They peck some now, but realize my fingers aren't food, that my fingers/hands bring food, and they are learning to love me because I bring them treats. ) I'm also picking some of them up, getting them used to that now, when they are young.
