Hello I am new to this sight and new to Guinea's. I have a hen that laid 21 eggs out in my woods she stopped coming back to roost at night and so did my cocks. They stayed down there for 3 days then came back up and have been up here ever since. I went down and grabbed the eggs. Any chance they are good and could try to hatch them or not?

Since you took the eggs away, it is extremely unlikely that the hen would accept them back. It is also very unlikely that she will use that nest again. If you want them to hatch it is best to put them in an incubator. You can candle them after 10 days to see if they are developing.
If you have a broody chicken available that can work very well. It can actually work better than giving them to a guinea to hatch. Properly stored hatching eggs can be viable for awhile but tend to start losing viability after 7 days. Store them pointy side down in a cool humid area and try to rotate them at least three times a day. One method of rotating is to place the eggs in a carton and elevate one end of the carton to create about a 45 degree angle. Change which end is elevated preferably at least 3 times in a 24 hour period. This method can be used to store the eggs for up to 14 days.
There are other methods of storing eggs that will keep them viable for longer periods of time but no matter which method is used, the longer the eggs are stored, the poorer their viability becomes.
