In Texas, Guinea Fowl do a fair job with ticks, snakes, and other varmints.

“Guinea Fowl
Three studies have examined whether guinea fowl feed on ticks in North America. Two of these focused on blacklegged ticks (also called deer ticks), while the third focused on lone star ticks. All three studies found that guinea fowl consume adult ticks, and two reported that this feeding reduced the adult tick population. However, two of the studies also examined the impact of guinea fowl foraging on nymphal ticks. Nymphal ticks are smaller than adults, so there is a higher risk of a person being bitten without realizing it and acquiring a tick-borne pathogen. Both studies found that guinea fowl did not reduce the nymphal tick population. Further, the guinea fowl served as hosts for nymphal ticks, which may increase the number of ticks in an area. Because of this, the studies concluded that guinea fowl are not effective at controlling ticks or reducing the potential for acquiring tick-borne pathogens.”
