Guineas are aces on ticks, so I've heard. Keeping them around is not easy. You can build a safe place for them to sleep but that's no guarantee they'll use it. They have the world's most annoying repertoire of sounds, too. Except maybe peacocks.I am tempted to get guineas to help keep the fleas down as well. I'm not sure if I can keep them alive though. I may do it anyway. They arne't expensive so if they live... then it's a win. I just have to build a place for them to sleep at night.
