My 8 week old chicks have been in their new coop for 3 weeks now. The run is still under construction, so they're in there all day, which is fine; there's plenty of room and they seem very happy to have a window on the outside world. Question: are chickens like other caged birds in that they will entertain themselves with a mirror? My chicks are fascinated with the reflective back of my cell phone (Buffy, in particular, never misses the opportunity for a close up), and I thought our old full length mirror, on its side, might entertain them. But then I thought it might freak them out and agitate them. Anyone ever given their chickens a large mirror as a toy?
