These Heat packs supply up to 72 hours of heat! We can add on to your order. 
If you are ordering hatching eggs during times when the weather is freezing, this is another safeguard for your eggs. 
 
If you are picking up locally and have a longer drive these are also a good option to add to your pickup! 
 
Please note that if you are having chicks shipped, these heat packs are included in your pricing already.
