chicks eating a LOT & one being very aggressive

when you get ready to switch them, I recommend that you start to mix the feed. Start out a few weeks before your switch date by mixing in a small amount of the gamebird/showbird feed. This will allow their stomach to get used to the feed. Then every few days, gradually increase the gb/sb feed until you have more sb/gb feed and less of what they are currently on.
I once changed my birds feed overnight because I overlooked the amount I had on hand and the store I normally get my feed from was out, so I just picked up something that I thought would work. The next morning they had diarrhea so bad, I had to run out and get the starter feed they were on so they wouldn't get dehydrated.
