We're wondering what animals are most ideal to have for gardeners? We are not interested in meat or eggs, mainly just in fertilizer, bug/pest control, etc. We currently have two goats, so I believe we are covered with fertilizer since goats are supposed to be one of the best. I hear chickens can be very damaging to gardens. Are there any other types of poultry that might be ideal (ducks, turkeys, etc.) ???
