Hi everyone, I have a question, just got 6 new chicks, 3 Buff Orps and 3 Aracaunas....anyway, I was doing some reading about grit for chick. The chicks are on non-medicated Manpro Chick starter and I didn't see grit as an ingredient. I also read that introducing grit early helps stimulate gizzard development, so I thought I would put a little sand in the corner of their brooder for them to mess around with...well they really like it! They are picking and pushing to get to it, but now I am worried they may just fill up on the sand and either cause problems/prevent them from eating their starter properly. Should I forego the grit, or let their instincts be their guide in diet selection. They are coming up on 1 week old. TIA!
