Hello, My daughter hatched chicks for her science fair project and out of six eggs three hatched! two of them are dead.. one day apart from each other. The first one hatched on March 31 and the second one on April 1. Third one is still alive but a bit week. Why did they die? is it because children were touching alot? or they didn't have enough heat? or proper food? we were giving them flex seeds. and vinegar water. Any tips to save the third chick would help. Thanks.
