Hope you got this straightened out and sorry you had to go through it. I am a clerk at a post office. You should not have been charged to pick up your chicks. A package intercept is when you are either changing the address on a package mid way or holding it somewhere in the middle of delivery. This does not apply to live birds at the post office they were going to in the first place. I hope that this was someone new and confused.
i agree, like i mentioned in my earlier post, it didn't seem to apply to this situation..
