I can see that considering there heads are probaly a bit heavier in relation to there size compared to other breeds also. I still dont see them as a fragile breed though. Maybe not a good free range breed since they would be an easy target for predators considering thier vision is obstructed and they cant fly. They didnt seem to be the most alert or smartest breed when I had them. I still keep afew hens beacuse when it comes to setters and mothers you cant beat them.
