Question about guineas...

Sorry for posting in the chicken section. The guinea section doesn’t seem to have a lot of traffic.
I have 4 guineas that survived the predators from last year. They are in a coop to keep them safe and they started laying eggs. They are laying about one a day and I have 7 today. However, I don’t see them sitting on them. I looked online and I found a source that says they don’t get “broody” until they have about 30 eggs. Does this mean they won’t incubate until the nest is full of eggs?

Yes, that's right.  I have had guineas for years but never had one go broody.  They aren't known as the best mothers either in my climate due to it being much wetter than their original land.  

Yeah I think a lot of people use an incubator or chickens for that. I know a couple people with guineas and the other issue is it is either hard or they don't know how to recognize if there is a male to fertilize the eggs. Around here the snakes get a lot of the eggs 'cause they just pile up.
