Yeah Thanks kezo for the reply, I’ve ordered a net should’ve here on the next day delivery, going to use that at the moment, however my Son will make a good thick wire type guard..
Have a look on YouTube how crafty Herons are, I know I’ve lost a pond full of fish to them, however see them in action is amazing..
Oh and the old decoy plastic Heron thing don’t seem to work after watch the vids..
