Shipping & Returns
Shipping & Returns
All livestock ordered between Monday and Sunday will ship out the following Tuesday or Wednesday. For example, livestock ordered between Monday the 1st and Sunday the 7th would ship out on Tuesday the 8th or Wednesday the 9th.
For the health and safety of our livestock we only ship on Tuesdays and Wednesdays. We’re unable to hold livestock longer than one week.
All livestock is part of our Arrive Alive + 72 Hour Guarantee. We must be notified within 72 hours of any issues or we will be unable to process your claim.
Livestock can be fragile. If your animal does not meet our standards at the time your shipment is being packed, we will notify you and give you a credit toward another piece of livestock. Our goal is to provide you with the healthiest livestock possible, and we’ll do our best to ensure it gets to you safely. Cash refunds are not available for livestock, only credit toward other livestock.
