just like to report that Serena and Bruno managed to kill my latest flock of 6 chickens that I had reared in place of the previous chickens they killed a few months ago. This time I had fortified my pen, re-did and replaced all the old wire with new chicken wire and I buried a layer of wire 40 cm into the ground and pegged before back filling.
Got home to find that Serena and/or Bruno had actually "eaten' through the wire with their teeth to make a hole big enough to get at the chickens.
So upset because I thought I had done enough to stop the dogs from killing my chicken. Not sure if I will bother with chickens again. Its a shame because I love fresh home grown eggs and chickens are a good stress relief.
I will probably return the chook shed back into its original aviary for my finches.
