They are almost 2 weeks old, 26 of them all seem ravenous, eatting lots of chick starter, probably at least 2-3 cups day, seems like I constantly refill their feeders (no, they never run out) I give them 2 hard boiled smashed egs twice a day, devore it in 5-10 min. very active and growing like crazy. They get grit sprinkled around, maybe a handfull a day. Just seems like they want more to eat????? Is there anything safely I can give them or just quit worrying?
