I had 3 hens go broody on me last fall. Two of them hatched eggs while the last gave up in the cold weather. It looks like my hen that we call Black Betty (White Rock crossed with a Silver Sebright) might be going broody. Last week I spotted her in a nest box pulling eggs under her like she was going broody. Then last night she slept in a nest box with fake eggs and stayed there through this morning. Something tells me that I'll be saving up my fertilized White Rock eggs for the next few days just in case I do have a natural incubator on my hands. Now I have to build her a brooding box and get her interested in sitting on the eggs in there.
