LOL I thought of your post after I placed my order and thought about the heat pack the whole time. I thought I should double check on the heat pack because I assumed it would be included. (I forgot, prior to shipping, to check) I can't believe they charged you for one really. I actually looked for it when I got my chicks just in case because I wanted to say whether people should ask for one like you did. I got a call saying that my chicks would be delivered on SUNDAY? I don't know of anyone who delivers on a Sunday so I was sure that they would be sitting in a post office somewhere. (heat pack? heat pack? running through my head) I expected at least 1 dead chick, but they were all quite LOUD and happy and I was relieved.
I have never shipped chicks in Feb. Pretty sure it's always been April/May for me and this is the first year I lived in a place that was colder than my last home. They have done good by me so far. But the more informed the better about shipping chicks.
