I raised three chicks from about 10 days old, and now have two more. One is an Olive Egger - BCM/ Am mix, and one is a hatchery EE. They are still indoors in a brooder in my laudry room, and every nigtht when it starts to get dark, they become so vocal. They sound like "real" birds, singing and chirping for about two hours. Loud. I don't remeber the other three (BR, Leg, and PR) doing this at all! They go on and on....... is this a breed thing? I don't think they are in distress or anything, but I'm not sure. Anyone else have this experience with EE or Ameraucana mixes?
