Ah I missed that it was that far in. Don't swap eggs for any length of time. They will need to be removed for a bit to get everything shifted if you really need to move the hen but shouldn't be off heat for more than 15-30min.
Here is what I would do then:
- If you're committed to this particular batch of eggs and really have to move the hen, have an incubator on standby in case it goes wrong, because it definitely could.
- Build or find a nest box insert that she can be carried in that can be removed at night but roughly fits her current nesting space.
- During the DAY, pull her out and then carefully take eggs out. Put the box in the correct location, move the familiar bedding into it, return the eggs, then return the hen and let her move back onto the nest herself. Check that she actually does and don't just leave it. If she scoffs at the new setup and leaves for more than an hour to hang out with her flock, it's probably incubator time if you want to keep the eggs.
- Assuming she sits, then at NIGHT carefully take the eggs out from under her in the dark to transport them safely an separately. Then do the towel cover over the box, take the box out with her in it, and place into the new location. Keep it dark and return the eggs under her by sliding under her wing. She should shift the eggs where they need to go in the dark and then should be ok with the new location in the morning.
- Put food and water by the box so she doesn't have to move to eat/drink. Letting her sit in the nest for a day or so without having to leave will help her get used to the new location.
The reason I like to move the hen in the box rather than simply toweling the hen directly and trying to get her to go in a new box in the new location in the dark is that she is very likely to have a freakout during some part of that process due to too many things changing at once.My boyfriend is really worried about the chicks droppings/food and water in the coop since it's not set up for that and can make a mess. So moving them after seem's like a potential option. How long after did you move her and the chicks to the brooder? 24-48 hours? Until they all hatched? What did you do about food for the chicks who had hatched in the coop before you moved them? Sorry for all the questions
