Ok, I have a non worming question (but I have really appreciated all the info. I love that I can constantly learn on this thread!!): Now that I am sure that my broody is really broody I'm going to be getting some fertile eggs for her to sit on. My question is: is it really best to move her to a separate pen? Should it be within the run still so that she can intergrate the chicks easier? Should it be completely away from everyone else? Right now she is in the favorite nest box (of course!). I managed to get the last egg from yesterday and the first laid today out of the nest when she was eating this morning. I wondered what would happen when she returned to the empty nest and well she just stayed in there, waiting for more eggs. And so yes, the other girls just squeezed in next to her! I'm sure there are three under her at least. I don't know if my other CM laid today. (the broody did NOT lay yesterday).
Thank you !!
I also have a broody! I will be speaking (typing) from research, not experience. Ive decided to let her hatch a couple. Ive built a covered with wire wood box in the pen. I gave her a nest box, food water and grie.
I've removed the eggs shes been laying on. I did this because I know she was broody and laying all week. I also know that even today, others layed in there. I do not want to chance it that some eggs began developing monday, and some would begin developing today...
I picked eggs yesterday and today. Put them in the box. I moved her in! I waited about 15 min while she settled. That was about 1&1/2 hr ago.

I will periodically keep checking to be sure she keeps laying!
Im very excited! It will be the first time for my family.
Good luck! Hope I helped and things go well for you and your girl!
