Last night I put some sprigs of kale in with my 3 week old chicks. The sprigs were covered with aphids. They LOVED them! Is this okay at this age and how much can I give them. A lot of info says to give them chopped hard boiled egg, insects, worms but nothing says how much of this. I feed them Purina Flock Raiser and throw grit ontop. How much of the extras can I give to my six girls???? Thanks...
