I woke up this morning to put my 6 week old chicks into the run and one of my americanas was dead. I'm not sure how it happened. I have 3 separate breeds and it seems to me that they "hang out" with their breed. I only have one americana left and I'm just wondering if she will be okay. They are all the same age and flock together no problem, but it was kind of sad seeing the others explore together and she was looking around more by herself.
