When you order a mix of chicks from a hatchery, and they have roughly the same appearance right out of the shell, does the hatchery do anything to "mark" them so you can tell them apart at first? Or do you have to grow them out a little, then separate them? I ask because I'm going to be ordering my first chicks soon. Six Pearl-White Leghorns and some CX meaties. I believe those will be all yellow chicks. Should I even worry about separating them at first? I will be feeding medicated broiler starter and I'm unsure how long the layers should be eatting that. I don't want the layers getting trampled by the baby pigs, so I was considering separating the two groups very early. Ideas? Suggestions?
