I did read on Ideal's site that they might ship early. I got ready just in case. I'm in Texas, not really far away from them by Texas standards, but me driving there and back same day wasn't happening at this time. My chicks left Ideal approximately 9:00 pm the evening of their scheduled ship date of June 28, 2017, arrived at my Arlington, TX PO 7:00 am the following morning. All 25 were in great shape when I got them home, before 9:00 am that same day. I wrote a detailed review on a thread in the forum here dedicated to such.
A day and a half later, and all 25 remain active and content. Got exactly what I ordered, but I did adjust my order slightly to hit the 25 bird mark (quarter box). I think I posted a pic of my invoice with the shipping charges too. I know I get a break in shipping since I live closer.
If I only wanted three chicks, I'd understand the premium I'd need to pay for that. Packing up three very fragile living birds takes as much care as packing 30. Maybe more if you have to add heat packs and purchase extra padding in a form other than living surplus chicks. Such small shipments will invariably have higher mortality rate, and the hatchery must also account for replacements or refunds. They are in business to make a profit. USPS has limits on the sizes of the boxes, both how large/heavy and how tiny they allow. The box my 25 chicks came in was roughly a foot square by maybe 4 inches high. Can't get much smaller than that.
