we had a buff orpington that died suddenly(heat maybe? we live in southern california) and a friend had thiers die too.(don't know how) are they not long living? (i mean, bad luck and that because ours was like a yearand the other was like still inside maybe) or are they prone to sickness? heat? they are definetly fluffy and iv'e seen pics of them in snow. when our other 4 get oldland stop laying, we may get a new one, i like the breed. also, we have a dirt lot behind our fence with cyotes and hawks/falcons fly over. we've never had any problems with it before but will the bright yellow be a problem? thx!!!
