I just checked my broodies. It is a rainy dreary day here, AGAIN! I am sick of this weather, and it is in the forcast for at least 3 more days. Anyway, I did see the one chick I saw yesterday, and I saw another egg shell. Two growling broodies, and I do not want to mess with them right now (in the rain). I know they are hatching, but not much more. So, no pictures yet.
Tim, I would move them. But only do it at night. I kinda tucked their head under their wing as I moved them (at least made sure their eyes were covered and they were in the dark). This worked well for me. I am using a rabbit hutch type enclosure, and it is working well. With my Silkies I used a dog house, and it worked well, also. Could you just make an enclosure .... say a large cardboard box in the garage? I would use a box like one from the furniture store, (huge area then). That way the broodies can get up and move around when they need to. If your hens have several different eggs of different dates, they are gonna be hatching for awhile, it sounds. It would probably be best if you take the chicks as they hatch (when dry and fluffy), so they will continue to sit.
I dunno, just my opinion.
