what a question!!! mine do not eat ticks but other people have had success with that(mine turn up their beaks and get offended!) , but mine do love japanese beetles-in fact i can't seem to pick enough beetles for them during that time of year. i think they are amusing and their crazy antics are a hoot. i love to watch them run around-ever seen a guinea run???. i keep mine in a coop with chickens and peafowl, all is well the guineas are in charge. they are adorable in their own unique way. the noise they make-they are loud! some people eat them, i have not tried but they are supposed to have all dark meat except for the white ones. they chase and torment the neighbor's cats who are TERRIFIED of them. we eat the eggs-everyone loves them; they have a flavor to them which i think is gourmet. my cousin's wife likes to collect the feathers-i guess she uses them for crafts. i'd reccomend getting them as keets instead of adults if you get them because they'll be easier to "train". mine keep me on my toes chasing after them and keeping them on our property-the neighbors love to watch me guinea herding so i am providing free entertainment unintentionally. i have fun breeding them because of all the color varieties and the genetics(not that i've figured THAT out well though yet!). i have pearls, lavenders, royal purples, an opaline, a coral blue, a slate, browns, and pied (pearl and brown). mine hate snow and rain too. i enjoy selling keets to other small farms and meeting people. so there are many reasons to keep guineas, but there are also reasons why it might not be the best choice so it's best to consider your circumstances(and patience) before committing to the joys of guinea ownership.
