I have a question about raising chicks...I have chicks in varying ages but the older and middle ones are wasting a LOT of chick crumble feed...I really need to get a grip on this...I have 10-12 week olds and 4-6 week olds all still on chick starter crumbles...they flick/scratch/waste so much! I have tried different feeder containers but even the 2-4 week olds inside in bins waste a lot of food...question is...at what age do you change them from chick starter crumbles?...and what do you graduate them to? and what do you find to be the best feeder for the older chicks but also to minimize the waste? or...any other suggestions? I even have drawers/pans to catch some waste and sift and re-feed (YUCK!!! I just don't think that is healthy but when 16 chicks go thru 30 lbs in one week ya gotta do something!!!)
