At 8 r 9 weeks they can have small amounts of treats. Be sure to put a small shallow dish of chick grit out for them free choice. That way they can get it if they need it. It is amazing how they seem to know what to do.I have been working non stop when i can to get my coop built and their run. They are running out of space so quick in their brooder..... So should I just throw some in their sawdust? What's good to start out with for treats?
