I've heard that the rule of thumb is 10, but there's NO WAY I can have that many. Can I have 3? We have a MAJOR tick problem in Pa, amd our dog was just diagnosed with Lyme's Disease. We want some guineas to kind of "patrol the area" for ticks. We don't really want anymore than 3 truthfully. I'm hatching chicks in Spring. Can I hatch them with the chicks and just have them grow up thinking they're chickens?
