I've never had a roosting area for my chickens. They always preferred to sleep in a pile and were never very interesting in roosting. Now that my rooster is gone the 4 idiots left are completely clueless about how, where, or when to sleep. I'm going to put a perch in their sleeping area then politely "escort" them in there nightly. My question is what is the best thing to use for a roost? Can I use a 2x4 or do I have to use something round. I'm getting conflicting answers from my nominal research. A little bit of background, the sleeping area is about 5 x 3 x 4 and well ventilated. It has been home to the flock (ranging from 3 to 4 decently sized chickens) for the past 3 years with no issues at all. They are free ranging in my back yard and when it is cold I house them at night in the sleeping area. Thanks in advance!
