If so, what would be the best dog to get to keep rats away from my chickens? One that will not harm my chickens or yap alot out there. We live in the city and rats like to harm my baby chicks now and then. I am raising Serama's and bantams. I am tired of finding my yard dug with rat holes and then now and then a bitten baby. I don't leave food out there any more at night so they get nothing to eat. We live a city block from stores with dumpsters and long before we had chickens, we saw rats around here and possums. Now today I am mad. My little silkie is in the house on antibiotics but not eating and it has me really upset. I put traps out but they just come back. We can't have a cat out there as it won't stay in our back yard probably. Plus don't cats kill chickens too? Any help appreciated!
