Thanks for the info Glad I can continue the supplemental stuff- my hen seems to be confused why her daily tablespoon of yummy food stopped lol I put a small clump of dirt I dug up outside in the pen for them to use as grit, mama has already been scratching and showing it to the baby. I think i will put some chick grit in also for good measure.We do... everything the hen got as treats before we continue with the chicks once a day, we just run it through a food chopper to make sure it is all in little bits... the hens absolutely love it for being able to show the little ones how to eat and such. But we only give it once a day, and not in great quantity so it doesn't replace the chick starter. And our chicks are raised on sand, so they get grit every day just by pecking at the seeds we throw on floor for them (again, the hen likes to teach them how to scratch after about day 2)... but if you are raising chicks on other bedding you may want to get some chick grit (available at feed stores and Tractor Supply) and place it in their area so they can have it when they want it.
