Hi everyone, I need help again with another unforeseen poulty situation 
I have a small, mismatched flock of rescued and adopted chickens. I started out with three ex-battery hens, who were very good at laying eggs every day. After a while, someone brought me a small, rescued rooster. I thought my production hens would never go broody and kept removing eggs every day. But one of them started hiding her eggs and eventually hatched out 3 chicks
I thought that was extremely entertaining and probably a one-off. This hen hasn't gone back to laying yet, and all my other hens(Brahma crosses and pullets of undetermined breed) are either too young or on their winter break. Only one of my production chickens kept laying every day through the fall and winter. Admittedly the winters here are extremely mild and the weather is actually some days the same as summer in Holland (where I'm originally from). But now she's decided to go broody as well! I realised this when she didn't go to roost with the others but stayed in the nest box for the night. Since then, I haven't seen her get up or even move.
I had been taking her eggs every day, so she was sitting only on a couple of plastic eggs - and one of her own eggs. I wasn't sure what to do - whether to stop her, just leave her to try and hatch out that one egg, or to get more fertile eggs for her. I tried to find more eggs, but there were none to be found, everyone's hens seem to have stopped laying for the winter. In the end, I decided to pull the three eggs I still had out of the fridge and put them under her
I did research and found a lot of threads on here of people saying that they hatched eggs that had been in the fridge. I realise the chance of them hatching is lower, but at least it's higher than the chance of plastic eggs hatching
I'm just wondering... will there be a problem with the age difference between the egg she already had and the eggs I put under her? I think there is a 1 or possibly 2 day difference, so they won't all hatch on the same day (if they hatch). If she has one chick and the others show no sign of hatching yet, will she abandon them? If so, what should I do with them if they did develop? Just keep them warm until they hatch or should they be put into an incubator? Also, if they hatch later, can I just put the chicks back under her or would I have to raise them myself?
I also find myself wondering if she's really OK... I have had a broody duck hatch 11 ducklings just a week ago, but she behaves differently. The duck left the nest pretty regularly to swim and eat, and she reacted when someone came close. This hen just sits as still as a statue, at first I was actually afraid she was dead! She doesn't even move her head when I put my hand in, only when I tried to take the plastic eggs did she react. I haven't seen her get up and go to the food or water at all. It is pretty far away. Would it be a good idea to put food and water close to her?
This is her:

Thanks and merry christmas/ happy hanuka!
