Ten of mine are going strong. The runty last one to hatch died a couple days after hatching. It just kept getting weaker and weaker, so I knew it was coming. I have 5 chipmunks, 2 yellows, and 3 buffs. The yellows hatched from my welsummers eggs and the buffs from my black star. The others are hopefully a blue egg layer cross. It will be investing to see how they all grow up, and who ends up being roosters! A guy on a Facebook group of mine had to quickly get rid of 16 chicks (15 olive eggers and 1 American Bresse) hatched around new years. His mom had passed away and he had to travel to the funeral. So sad. So I took all of them and added them in with mine...Lots of chirping going on! I will keep a few and sell the extras.
