I picked up my chicks about 24 hours ago and they were very vocal. They've been in the brooder all day, eating, drinking, getting their leg bands removed and under the warmer...but tonight they have been silent. I keep checking on them thinking something is wrong. Am I just being paranoid?!? Is it normal for them to quiet down once they've had time to settle in? My last hatch was noisy all day long so I think that's why I'm so worried.
