That's great, and probably the best way to go. The guineas who are raised by hens are much more inclined to roost inside at night. In fact, they'll want to stay near mom,
forever. This can cause some conflicts the following year, or sooner, when mom gets broody again. Or, if a guinea hen she raised gets broody. They have different instincts and behaviors from chickens, and they don't get it when mom
chicken doesn't act like a mom
guinea. It can cause a few headaches, but it's pretty easy to deal with if you have a few little pens, or tractors, or mini-coops, someplace to put moms and eggs and babies where they can be safe from interference from other birds in the flock.
Hen-raised guineas are also more likely to lay eggs indoors in a nest box, rather than out in the brush somewhere. Note that I only say
more likely. One thing I've learned with guineas, is they are hard to predict, and very often contrary to the point of being downright perverse.
For example, with a nice, warm coop available, most of my guineas were staying indoors with the chickens at night. At least while the fall and early winter weather was relatively mild. Then it got colder, there were high winds and freezing rain. So where were the guineas at bedtime? Up
on the roof of the coop, or out
in the trees. Evidently, before the bad storms, the weather just wasn't
nasty enough for them to sleep outside!
