When I brought the chicks in tonight, they seemed agitated. The two little "eggers" especially -- they kept making this sound, like "Deee deedeedeedee deedeedeedee deee" (imagine it being whistly and high pitched). One of them even hopped up onto the wire between them and the big girls and ran to me to be picked up! She seemed to be content to be held, and was quiet for a while when I put her back. I did turn the heat light on (it's about 60 deg, and falling now that sun is down) although I've been leaving them in the dark at night for about a week. What do you old hands know about this?
