I love my guineas, YES they are LOUD but they are funny and I have not seen a tick since we got them and although I am not sure how this could be related to our guinea the mosquito population since guinea ownership 3 years ago has dropped off dramatically. Mine live with the chickens and turkeys (free range) sleep in the barn at night and play nice. I have heard horror stories of guineas and chickens, if that day ever comes guess I will finally figure out what guinea tastes like! But they are great. Cold hardy at least to my southern Idaho temps.
