The bantam cochins don't do so great in the mud being as they are low to the ground and heavily feather legged. On the broody thing when I had the older splash girls I had a few try to go broody on me but I never used them for broodies. The Mille girls are all too young to really be hitting the broody thing but I have silkie hens the same age that have raised 3 broods so far so I would say not as broody as silkies. The silkies are always going broody and will set on anything.
