I have 9 new chicks,two weeks old today. They are voracious eaters! Was wondering if anyone could tell me if giving them one cooked egg yolk a day was too much (one for all of them, not one each)? I know too many treats spoils them, but they are ALWAYS hungry, even with plenty of chick starter food on hand, and they are getting a little aggressive (okay, alot aggressive!) with each other over food.
