I have just started a small backyard hatchery selling black sex-links. I have lots of orders; most are local pickup but some want them shipped. I live in Central Texas and all the orders will be shipped within Texas. My question is, for those that have shipped a larger number of chicks, how much (with a shipping box) weigh for 25 and 50 chicks. Or this might be easyier to understand, how much does a chick weigh (dual purpose, Barred Rock x with Production Red) and how much does a box typicaly weigh. I was thinking of maybe doing a flat rate since all the shipments are within Texas, but don't want to end up losing money on it. Any help would be much apreciated!
