I know that eggs and day old chicks are frequently shipped through the mail. Does anyone have any experience shipping fully grown and mature hens. We are moving from Florida to Colorado and are taking our backyard girls with us. However, ideally I'd like to ship them ahead of time to a receiving friend until we get there- we are planning an extended road trip and taking them in the car with us and the large dog and cat is not an option! Any advice, stories, tips, experiences doing this would be greatly appreciated! I am thinking that they can be shipped overnight as live animal cargo- perhaps two to a box? We have 4-5 total we are bringing. Thanks in advance!
