Our chicks are now 3 weeks old. They are now in a large, clear rubbermaid container with a wire lid with plenty of room to walk around and I even added something for them to roost on (which, they love). They're so well behaved during the day and I get them out several times a day. Anytime I lift the lid off, they immediately fly out and perch on the side of the box. They fly out every chance they can get. The problem? Every single night around 8pm, they begin chirping and carrying on like crazy! They get so loud that we can't hear tv. They'll also run from one side of the box to the other and peck like crazy on the side of the box. I've tried moving them into the bathroom where it's pitch dark, but that doesn't stop them. I don't know if they hear us or what it is. The ONLY way I can calm them down is to take the lid off and let them perch on the side of the box. The problem with that is that everytime my dog (a Sheltie) walks past them, they try to fly onto her or they jump down onto the floor and chase after the dog (Cricket is her name). Cricket is scared of them now. They also calm down if I hold them. I've tried putting the heating lamp in there, but they get away from it. So, I know they're not too cold. When we go to bed and nobody is downstairs and all is quiet, they immediately settle down. Are they just spoiled rotten or is something else going on?
