I ordered 9 cochins and 9 silkies from Valley Hatchery -- received them on a Friday afternoon via USPS. One died in transit. Not abnormal. 13 more died over the weekend! I only have 4 left! The chicks were lethargic, and I suspect diseased (parasites).
I have experience raising chicks (safe & clean brooder box, warm heat lamp set at 100, clean water, organic starter feed, pine shavings for bedding, etc.), and I can tell you that they didn't die from lack of care.
This was my second order from Valley Hatchery. They refused to replace any of the chicks. I tried to leave a Google review, but cannot find where to leave one. So I am leaving one here. Consider this a 1-star rating. I won't be using them again. Too costly.
