I want to get some quality orpingtons of different colors next year so I'm going to have to get hatching eggs. Do I need to wait until temps have increased enough they won't get killed in a cold mail truck? Is there a shipping window folks aim for to get better viability from their eggs? I'm probably going to have to get eggs from several sources which means staggered hatches. What do you do about upping humidity for the early hatchers when some of the eggs are far from hatching? I know to let them sit for 24 hrs to let the air bubble settle and temps even out. Any other tips to increase the hatch rate of shipped eggs?
