My guineas and my chickens are shareing living quarters this winter and so far they are getting along fine. This spring I plan to turn the guineas out to roam. I have EE and golden comet hens .I am getting a few blue/green eggs now. My guineas were hatched in July and august. I have 12 guineas in the pen. They are loud and if any strange animal or human comes near their pen they set off a terrible loud noise. I think if any thing was to enter the pen at night I would know at once that something was wrong.
