I've had my BO's for about 4 yrs now & they go broody.. alot. Since I've had my bantams.. they are worse than the Buffs I don't really have I clue what breeds they are,but they can just glance at a pile of eggs & they're broody. Even my little mutt bantams are like that.
Wow, our Buff Orp is 2 now and has NEVER gone broody. Our Jersey Black Giant goes broody at the drop of a hat. So I understand about your bantams. Good luck!
Oh geezzzz... I know what you mean. My banties are nightmares. They will all pile up together, on top of each other, fighting over one nest. It's just crazy. And don't even think about sticking your hand in there unless you want to lose a finger.
