I ordered my (25) baby chicks (pullets) three varieties (BO, BR, & NHR) in mid-June from Meyer Hatchery, for delivery July 30th. They sent 42 baby chicks - not one fatality (yet) - and all the correct varieties just too many of them!!! I'm thinking they put in extra for warmth or to get rid of some suspected roosters or to compensate for DOA...but I was SHOCKED to receive 42. They are all healthy and energetic on day 3, I started them out with lukewarm sugar water immediately, and medicated chick starter mash. They took very quickly to both, although I did dip all of their beaks into some water when transferring them from their mailing boxes to the brooder. They are cute as buttons and quite content (so far). Don't worry too much, although I understand because I was a basket case.
Our PO doesn't open until 8:30 but they called at 6:45 - they'll be great about it if you notify them ahead of time. They are there before they open, and chicks aren't the standard postal package so they do treat that sort of delivery a little differently. Talk to them about it to make sure.
How many did you order and from where?
Good luck!
