I am new to backyard chickens, and I am glad I found this forum since there is a lot of good information here. However, I am having a 'problem' I hope to get some help on... The 3 chicks are about 6-7 weeks now, and I have had them almost two weeks. When it starts to get dark, they seem a little anxious and make noise. It's not a loud noise or cackling, but more like a whistle. It's not really loud, but I don't want to draw attention to them either since I live in a city. They must make the noise for a reason and they probably not happy. The coop is about 4'x3' and 3' high. The coop itself is about 1.5' above ground and the run is underneath the coop. The strange thing is that they don't want to go upstairs either and eventually they get quiet and fall asleep on the ground.... They know where the coop is since I have kept the food up there. I also have a roosting stick (a real branch with bark so it should be too slippery) and I seem them on it so I know they can make it up there. The coop also has fresh shavings. I also put a light up there the first night to see if they would go up, but it didn't help. If I try catching them to put them upstairs they get louder... What can I do to make them stay quiet and go inside the coop at night? Here is a picture of the coop.
