My 4 month old Fischer's favorite place in his cage is right next to the window, and its not like hes trying to escape because he just sits on his little perch by the window and looks out at about the same time every day for an hour or so, even when the window is closed. I was worried he would be stressed out by the horses that come by the window but he doesn't move away or turn brown, they don't seem to faze him. usually when hes sitting there he turns the coolest colors Ive seen him turn, he turns bright green, light brown and purple with white spots all at once. Im not worried about him or anything, just wondering what the behavior means. Does anyone else have a cham that does this?
