According to my cousin who worked for the post office, they would call early in the morning to get the people to pick them up as soon as possible because of all the noise. He said he hated to have to deliver them when no one would answer the phone. Nois-y!I went and spoke to my local post office, and made out like I was doing them a favor to get the babies out of the post office. I joked about the chicks making so much noise, so they actually called me at about 5:30 am and met me at the front door with the box. May seem like overkill but it made an impression on them and I got my babies really quickly.
