I am a proud father to six 3 week old chicks(3 rir AND 3 ameracuana) I have 2 questions(well hundreds but only two right now)1. Can I start giving them a little bit of lettuce to help with the bonding process? 1a. Do I need to start them on a little grit? 2. what temp should I be at in the brooder at this point? It is at about 80 degrees. They are so cute and growing like weeds!!
