The puppy is a Great Pyrenees. I know you cant just bring a 2 month old pup and throw him in with your chickens thats just asking for trouble. My question is if i buy him/her do i need to leave them tied by the chickens for a little while? And is it very possible for the pup as i finally trust him/her enough to be "free" and do their job to work its way towards the highway?
Dog will not bond to chickens, at least mine do not, as limitation appears to come from chicken side. During most of day I would use confinement of dog with a fully adult standard rooster or two. Bigger roosters better. Periodically during day release dog among general flock under supervision and take time to patrol perimeter. At some point you will want dog to patrol at night so birds need to roost in dog proof locations for a while so no tie-cords during that interval. Upside from pup molesting chickens is it will learn alarm calls that will reduce response time to predators once dog matures. Tie-cord setup will have birds spread as I do so dog will have to be more vigilante than would be with a single cohesive flock of sheep. You want to avoid dog going into house dog or non-roaming mode as that can result in birds in perimeter being much less protected. At work on a single research farm we have about ten dogs (about half are GP's) that are generally kept singly with respect to herds of sheep and/or goats. Dogs and livestock are confined by at least two perimeters of fencing with inner usually being electrified. A riled dog does not always respect the electrified fencing so outer gives an addition buffer between dogs and highway bordering property. When said an done the fencing will be your first limitation so make sure that is adequate. Then even when dog is in place keep birds away from fencing if practical. With good fencing less dog is required as the biggest threat, other dogs. will not be able get in. Typically my biggest concern in terms of size is the 35 lb coyote but most consistent concern is Mr. Red Fox so smaller / faster / smarter dogs have been my route. Much more training was involved but it enables me to repel and sometimes eliminate bad guys that employ snatch and run. You will be having dead opossums and raccoons brought up but try to make dogs role easier by not having charges too spread out as that can make proper defending more difficult.
