Howdy and welcome from N. Central Texas! There is a good deal of information about training/dogs on this forum. I have a little Yorkie that I will never trust around a chicken. -personally think that terriers aren't a good mix for chickens (due to hunting instincts). I, too, had the dog first (and he's adored by the family) - so I just accommodate everyone. -dog resides indoors until a bathroom break is necessary (and I accompany so he doesn't dart for the birds). -chickens roam the back yard. When they're in the coop, the dog can run about the lawn for a bit. When they're out, he's in. -works fine. Good luck with your birds and Jack Russell! (many folks swear by good, thorough training - but I stick with intuition regarding instinct, personally, and keep 'em separate)
