I had them long ago and just liked watching them and enjoyed having something different than the rest of my flock....they obviously made different sounds and had a different appearance. It was a good conversation piece. I had intended on eating their offspring, but they hid their eggs and eventually disappeared, due to local preditors.
I plan on getting them again next spring.
My husband has been reading about them in, "Gardening with Guineas" and he informs me that we need to coop them for a laying season so they understand where we need them to lay, that we shouldn't allow them to raise their own keets, and that they will keep our garden vertially free of most bugs, without disturbing the plants (that part I have got to see).....they will peck the bugs off of leaves and it will appear they are munching on the leaves but upon closer inspection they are doing us a service.....Okay.....lets hope so. Also, they won't scratch, as a chicken will, so the ground won't be disturbed. And then their is the safety factor. They make awesome guard dogs (that part I do remember). They will be the first to sound an alarm when a danger arrives, such as a dog, chicken hawk or cat....even a person. The other birds learn to pay attention to the guinea's distress call and they all run for cover. That could potentially save your flock.
I am looking forward to having them again and being so very much older and hopefully wiser, I plan on doing it with something to show for my investment and troubles.
I know my chickens eat a few ants. Considering that guineas are supposed to loves bugs so very much, can anyone speak of guineas taste for ants?
