I am looking to sell some of my birds on a public auction site that I have purchased off of before. Is there anyone here that can offer some advice to a first time seller/shipper. Is there a certain company you would buy shipping boxes from? I am looking to sell a few 5 month old Tolbunt Polish. Also, considering the time of year, would you add heat packs and what do you put in for food and water? Any advice you can give me would be greatly appreciated and help calm my nerves a bitThanks so much!
