My experience with guineas is they will eat your garden. I had 60 adult guineas last year and had to sell all but 6 that I could not catch. My husband planted a large row of green onions, he went back to the feed store to buy more to set out, in the 30 min. he was gone the quineas had ate ALL of them! He plants around 1000 tomato plants (he sells tomatoes) and my sorry guineas pecked holes or ate most all of his first crop until I could catch them and sell them. To say the least he was highly upset! Those birds seemed to eat eat anything he planted, absolutly tormenting him. If I can't can't catch these last ones I am afraid they will probably be shot, he depends on his large gardens for income, so I really can't blame him, hopefully I will be able to catch them shortly.
