My chicks shipped yesterday from MPC. When I checked the tracking number this morning the only information was the arrival scan from the hatchery to their local post office at 7pm EST last night. I had the same thoughts-that they were just sitting in Cleveland....but my post office called me about an hour later to let me know my chicks were ready to pick up. I was shocked, that was only 12 hours later. Don't count on yours arriving today but don't be surprised if they do. They were packed extremely well and all happy, healthy, and alert upon arrival. I'm happy they got here today but they probably would have been fine even if they hadn't.
Most importantly, don't trust the tracking info. It isn't updated enough to be helpful.
Good luck! I hope they arrive soon.
