I'm going to have to live my broody to her coop pretty soon, should I leave her box and all or can I move her and the eggs into the nestbox??
I'm not sure what you are asking due to the typo...but if you are asking about moving her...and you really do need to move her from where she is at...I would do so now before your important eggs come. I would move her at night with her egg...literally transferring her and egg at the same time. Being a Silkie she will likely give you an evil glare and settle right back in if the brooding coop is nice with a comfortable isolated and quiet and dark nest box.
If you do not have to move her...don't. Some birds don't like being moved and will reject the new nest with eggs trying to go back to the old nest...however didn't you just get this bird from someone and essentially move her brooding across 2 farms? I'd be surprised if she bats an eye ...still best to do at night so she settles and adjusts quickly.
If you were asking to move nest and all to new coop, that is often a good idea to simply move the whole dog crate or whatever..I would carry her and egg separately as she might freak and crush the egg in transit if she senses the nest is "falling" by sensing it is moving.
However if you've got a nice nest box that you want her and those special eggs in...move her and her egg now and let her settle before they come.
