Hubby made little holders for my dishes to be off the ground. The problem with that is your chicks might jump on those.
In this dilemma, I think I'd put a small dish in the corner of their hen boxes or somewhere the young ones can't or won't get to it.
I had an incident with two-week-old baby chicks being brought by the hen to the oyster shell dish that was tipped over and scratched around. They ate it for probably several days and wound up lame. We treated them with various herbs and did physical therapy for two weeks. Nothing we did could save them, as their leg nerves run through their kidneys. Their kidneys got damaged by too much calcium. We had to cull three out of six of them.
