Have you ever owned Guineas? Read my post, s-l-o-w-l-y this time for the answer to that question.
Guineas eradicated my tick problem on 10+ acres within a couple years, ranging every square inch of it. Granted, it's not the wilds of Africa, but it was brushy and tick ridden when I bought the place. Tick free now, so am I, and so are all my horses, dogs and cats. Your opinion of Guineas being tick predators being "propaganda" is just that, an opinion. But its fact/reality to many. Well, also your opinion.
Their uses are somewhat limited? LOL! Seriously? Free range eggs (for years longer than a typical chicken will productively lay), Sure, and almost every day, almost all year long, like most good layers? And there is a market to sell those eggs to those who will eat them? Guineas eggs do not have a distinct flavor that is detectable in foods that are cooked with them?LEAN meat, Sure, how long does it take to get to market size, how much meat? Chickens are not much better at this? keets, Chickens don't produce chicks? pest and weed control, Chickens don't do this too? alarm system? Sure, if you like an alarm system that goes off when the mailman comes, your children's friends come over, the dog goes out, the dog comes in, a leaf falls, or just for no reason at all. I beg to differ. I'm beginning to wonder if you've ever kept Guineas.
And don't most chickens just stick around close to the coop and wait for... oh, what's that junk they eat? Oh yah, scratch. Have ya seen the price of corn lately? You don't feed your Guineas any supplemental feed whatsoever?
Those of us that actually own and raise Guineas know the facts about their benefits And btw, my Guineas definitely got the memo, (all of the memos actually). They more than earn their keep on my land.
Your loyalty to them is admirable. As I wrote, I do admire Guineas too. I just think that I'm more realistic about what they are, and what they are not.
