Hello. I am hoping I am just a worried first time chick mommy like my friend is saying... My friend decided to put the chicks in their brooder outside for 'fresh air'. When she noticed they were dust bathing in the shavings she got them a big dish of dirt to dust bathe in. I have not fed my chicks anything but chick starter medicated since we got them. They are only 10 days old. It looks like they ate almost all the dirt. There is a little in the brooder mixed in the shavings, but we have 16 chicks and the plate she filled is over half empty. Will this hurt them? Would they know better. I know I have read a little dirt is good to act like grit for digestion, but they seem like they ate a lot. Please help. What should I do??
