hi!everyone.i am a new member.i currently have RIR and some buffs for my laying stock(6).they are enclosed with supervised play time.i have 70 acres with 32 acres currently fenced.i was looking for some poultry to let run freely on the 30 acres.we have horses and they have ticks every year.we also have possums,coons,foxes and hawks.the birds would have a barn for shelter and food but pretty much left alone.i was told guineas would work but i'm not sure they would be tough enough.what about some of the game birds?any advice would be greatly appreciated.thanks GB
