Seems to be quite a spate recently of foxes killing chickens.
We lost two chickens (in the middle of the day) after a few weeks of constant effort by the fox after an unsuccessful attempt.
Neighbours also lost 5 of their chickens (here in Hackett) and others in Ainslie have also mentioned losses.
Sounds like TAMS cannot do much because urban rather than rural.
Would be interested to see who else has had problems.
Apart from the benefits of eggs, scrap eating and garden scratching from chickens they are wonderful (and loved) pets for kids.
