I wasn't sure if I should post this in the raising chicks section or here, but decided it was more behavior oriented. My chicks are about 40 days old, and still in the brooder in the house, which is a very large cardboard box. Their latest thing is to peck at the cardboard walls with their beaks, which now that they are getting bigger, makes a LOUD knocking sound. Sounds exactly like a person knocking at my door. And they do this over and over and over again, for hours and usually during the wee hours of the morning when I am *trying* to sleep! I live in a tiny house, and they are in the room next to where I sleep. There's no better place to put them. But I am losing sleep big time and they are absolutely driving me nuts. knock knock knock, all night long. I've done everything from ignore them to check on them to shoosh them (which works great.... for about 10 seconds), and they aren't short on water, food, cleanliness or space. They aren't peeping or chirping as if anything is wrong. They are just obsessively knocking on the cardboard walls. Does anyone know why they are doing this? Aside from the obvious annoyance of it, I certainly wouldn't want to try to ignore them if they are in need of something, although I don't know what that would be. Has this happened to anyone else? Is there anything I can or should do? In case it's relavent, they are 7 Bantams, 5 of which are Silkies, and then 1 Cochin & 1 Mille Fleur D'Uccle.
