THIS IS MY ONLY MY EXPERIENCE. YOUR OUTCOME MAY BE DIFFERENT THAN MINE.

This is not good. I have done the same thing with some game hens. I moved them, during the day, to a new location and they came off of the nest in fear and never returned. Even a game hen, the broodiest hens, wouldn't return. (These hens were free-ranged, not pets who were handled but also not flighty of humans)
Here is why this happens:
A broody hen is in a horrible spot for a prey-type animal. She is an easy target and is pretty much glued down for around 23.5 hours a day or more. She is very alert and focused on the job at hand. She spends her day looking for potential danger and watching for threats because she is very flighty of predators during brooding. She is fully aware of her entire surroundings. During this time a hen will not vocalize while on the nest or leave the eggs but one time a day to eat and defecate. She does not want to draw attention. She is going through the strongest instinct that chickens have.In most cases she will not leave her eggs unless she fears for her life. If she is threatened she will fluff her feathers and make growling sound. If that doesn't send the threat away, only as a last resort, she will leave.
This is the problem. Hens know more about incubation that humans do. They have more experience. She knows that after she leaves them, they will cool off quickly and be ruined if she doesn't return. However if she felt threatened she won't return at all. This is the case for every broody hen I have seen leave her eggs. I have tried every technique with no luck at all. Once they are gone from the nest, they don't go back. Think about the "going broody" process, it is so strong that hens who some hens will do anything to hatch and egg. Most chicken owners can't stop the process even when they remove her for days. These hens didn't leave by choice or fear. Fear is a driving force for a chickens decisions. They are PREY. Once they are frightened of something, they avoid it. Now out of fear, she fears going back broody.
I breed and raise American Gamefowl. I have 15 years experience with chickens and have had countless broody hens. Most BYC members will tell you that game hens are among the most broody of all breeds (except silkies and cochins). I have seen several hens be moved (only in daylight) or frightened off the nest while brooding leave the nest and never return. Never once have I seen a hen leave her nest out of fear and return. I have, however, lost a broody hen to a dog attacking her right on the nest and directly (within ten minutes) put them in an incubator and hatched 6 out of 11 eggs that way.
I am sorry I didn't have more hope. I wish that I could have told you something positive. I just wanted you to know my honest opinion. Not that if the other suggestions don't work it may work for you but it didn't for me. I only hope you can appreciate my honesty...
Sorry again,

****For future reference if you need to move a broody hen (only a last resort): move her at night, with the nest's top covered, and carry the nest box with the hen inside to the new location. If you pick her up off them she may leave them in the morning so it is best to leave her alone during this time or have nests that can be removed easily. I have moved several this way and it worked well. Only about four hens in fifteen years have left the nests the next day.
