Hopefully she has gotten up by now, but it's very normal for the first few days for you not to see them get up. She probably has, just maybe hasn't pooped. I think they condition themselves to hold it, and the first 3 days, they barely move. The hibernation type thing is normal too, almost like they are in a trance.
I gave eggs from the incubator to a new broody (actually 2 new broodies) yesterday. One was easy. One didn't want to give up the 2 eggs she was on. I had to take a soft rag and hold over her head for her to bite while my other hand swapped eggs! Lol. The eggs were already on day 10. That's the longest I've ever incubated then given to one, so I hope they do ok. Both are sitting tight still tonight.
maybe she will let you candle them in a few days? How many is she on? Hopefully enough to spare a few if they are clear. If too many are clear, and you are able to check them in the first week or so, you can trade them out. They will usually just sit until something hatches. I've only had one broody give up early, but it happens. (I feel sure you will have an incubator you can pop them into! Lol) I had another broody that had all quitters when I checked on day 18, so I gave her 4 more, just in case she wanted to tough it out, and 3 of those hatched! So she sat for 40 days!
