We received 20 chicks from Meyer Hatchery on May 3rd. They all arrived viable but within two days time, we lost 10. We lost 2 Partridge Cochin, 4 New Hampshire Reds, 4 Welsummers I contacted Meyer and they replaced all of them. We received another order of 20 chicks a week ago today. Within the past two days, we have lost 3. 2 Blue Cochin and 1 Welsummer. It is past the 48 hours, so nothing will be done. We have several more that I'm pretty sure aren't going to make it. At first they were chirping and running around the brooder like all of the other's. Then they stop chirping, stop running around, get lethargic then die. I have another order for the end of June. After reading this thread, I may cancel.
