Yep, many good points put forward from above posts. But 'Strays' are a 'Blister on our Foot’, which sadly - I believe - is here to stay, and one that we will just have to put up with. Regardless of high ground or morals I’m afraid. No! I will never cull anyone’s bird. I hate doing mine when it is in their' best interest or has to be done. But I have to accept, like you all do have to, that this 'Blister on the foot' is a small pain to any other options open to us. So like the ET. Get over it, it's here, and will stay a blemish on the foot. No two ways about that. Liken it when- as a carpet / floor fitter - asked to take up old lino / carpet etc. We straightaway refuse, because it's like a 'Pandora Box' you just don't know what a multitude of sins may be hidden!! - even to move anything at all, off shelves, fridge, chair before laying a carpet we refuse.... Because the knock on effect could be very costly to the fitter if he does a good deed to help! So we don't / won’t do it! Likewise the cost in real terms would / will far outweigh any costs in regards of trying to enforce a practice - as it has now become - that doesn't sit well on our shoulders.
