She went through a broody period once before, she seems to be very inclined to do so. I do have two roosters. She'll probably go broody again in the spring and at that point we'll allow her to set some eggs, but really don't want her trying to raise chicks in the winter. I'm going to the coop often and removing her from whatever nest she hss taken over.
We haven't cracked the tiny egg, and may choose to keep it intact and let it dry out as we have the one from Easter. I am curious though as to whether it might have a yolk despite being so, so tiny. Or could be a difference in gender was pretty round, and this one has a normal egg shape it's just very, very small.
