Thanks for advice Karen, it is the bigger birds he prefers to chase. Think when letting him in the garden will take him on lead then at least I have control of what he is doing, just don't want him to run off when out on a walk, just want to get in under control now, I hope if I keep telling him 'leave' he will understand as when he picks sticks up and I say leave he drops them straight away, he is so good in every other way cant fault him at all.

How are Domino and Mazy getting on now, Misty and Oscar now never stop playing they have gone from one extreme to another.
