it's the thrill of the chase that hooks them.. not the taste of blood
one of my LGDs will lay with the birds all day long and never touch one.. but as soon as we butcher birds she's standing there wagging her tail looking for a piece of liver or the heart. She LOVES the meat.. but she would never think of killing her "babies"
One of the cattle dogs is another matter. She's fine so long as the birds are where they belong.. but if a bird escapes and is out and about in the yard it's game on.. she tries to herd it.. then chase it.. the prey drive is very strong with her breeding.. and if she manages to CATCH the bird.. well.. you better be faster than she is.. So long as the bird stays where it belongs she's fine and will ignore them
yup.. free roosters.. old worn out layer hens.. free ducks.. you name it.. just make sure the free birds never ever come in contact with your flock (risk of birds spreading disease to your birds) so quarantine them if you won't be butchering them for a few days
we pluck the birds and wash them off.. I prefer to gut them because i am parting them out anyway.. other people don't bother (and my dachshund has decided that smelly guts are fun to roll in...
)
I remove the heads because I want the skulls!
I grind up the feet along with the bones.. but with one dog you shouldn't have an issue with him trying to inhale the bird before someone else does so depending on how much he will eat at a time you can cut off the feet for later or leave them on
My aunt started me on using the extra birds for dog food.. the thing she does differently is that once she kills and plucks.. she rinses them with vinegar and water or lemon juice and water.. so it doesn't smell as much like "chicken"... I never saw where that matters.. but she swears by it
