I don’t have designated chick grit. Can I grind up eggshells or something for that?I would give them chick grit but until they are used to it, just sprinkle some on their food. Once they learn it isn't really food (a few days) then I'd keep a small dish of grit in the brooder. But sand it too fine to be used as grit. Do you have access to chick grit? Some feed stores have it and some don't. I had to get mine mail order. Parakeet grit will work for a while but they'vs nearly outgrown that. And wait on the fine sand for dust bathing till they understand grit. They can pack their crops with it and then they'll have trouble eating.
