I have about 22 chicks I bought from a hatchery (there all heavy/standard breeds) back in mid october... At this moment they are almost the same size as they were at 2 months old and not growing properly... I think it's beacuse I used to only feed them cracked corn.. But I just bought a 50 lbs of Blue Seal Grower Pellets, it's 15% protein. I also sometimes give the chicks Greek yogurt. Will they get bigger/grow faster with the new diet I'm using for them?
