I hatch a batch of chicks 8 weeks ago. The are mixed bantam. I gave several away and the ones I kept are A LOT smaller than the ones I gave away. The ones I gave away are probably three times bigger than mine. Also several of mine have died. Each time I blamed it on something I did. I was feeding them chicken crumbles that I feed the adult chickens. The people at the feed and seed said that would be fine. I just switched to start and grow and added electrolites to their water. What else should I do. The two I have left are under a light with the new babies I hatched two weeks ago. I hate to put them out since there are just two of them. HELP!
