This was 2 weeks ago - 2-3 day old CHicks from Meyer Hatchery. 1 was DOA. Sunny afternoon with sun on the box, to start, monitored by digital sensor thermometer. Outside they liked 92 degrees best, indoors 95. More calm under red UV light than an incandescent.. Most will be Brown Egg Layers. Can u find the 2 Barred Rock, and 2 Exchequer Leghorn? What other Breeds do you see? My pal Cher came for 7, I kept 8.
