I am so sad! We just lost a 2 day old blue cuckoo maran! She was our tiniest chick. Sadly my week old chicks crushed her and I had to break her neck to put her out of her misery. 
My 8 year old is heartbroken and said she was his favorite chick. We buried her in our garden and he is making a cross for her.
Just a quick question was she raised by a broody/incubator, or by a hatchery? And how old where the older chickens?
Was there not a better way to put her down? Could she have been saved? I dont think chicks should be killed until there is no possible way to save them. I have eggs in the incubator right now so I hope they all hatch out healthy
