I used three broodies this year. I don't know if it was the breeds or personality but they all were okay with me checking eggs and chicks. I got a few pecks that didn't hurt, some verbal complaints. When I picked up a chick and it was cheeping I would get some ankle pecks, but again, not painful.
Zacchaeus was raised by adult hens and minds his manners. They finally accepted his advances, but he had been tidbitting them for weeks before it paid off!
No broodies, just the pullets. Not laying yet.
