You can try but I doubt it would work. There are always exceptions to every rule but for the most part, guineas do not take well to having their nest messed with. The most likely result of moving her and her eggs will be her abandoning the eggs. Some people have had some success by putting the eggs and the hen inside a large dog carrier and it has not worked for others.I have a similar problem, but a little different. My Guinea is sitting on her eggs in the middle of our garden, and it is starting to rain here in Kentucky. I wonder if I should gather up her and the eggs and put them in a coop, hate it they are in the weather.
Good luck.
