My little Buff Orpington (8 days old) caught and ate her first spider. Aw they grow up so fast! I figured she wouldn't be able to digest that very well without chick grit so I offered some in a little dish. All chicks had a go at the grit. Was planning a=on not starting the grit until two weeks but figured I better if the bug eating begins so early. Am I on the right track? Any danger in the chicks who are not eating anything but chick starter getting a little extra grit?
