I have my brooder in the house with my hen and roo in. The kids and us are around them all day and i guess they have gotten use to the noise we make. When we go to bed and all is quiet they start cheeping like crazy. I was about to have to move them into the garage so we could sleep but my new brooder is too big to move in and out every morning and night. Soooo for about 4 days i tried every thing to get them to stop. I finally turned on the tv and they were quiet. Its the only way to keep them from cheeping. I have couch potato chickens.
