@Zayne Hope your chook gets better, if by any chance you need a smallish container to keep her in inside, we have a small rabbit cage (indoor style) you can borrow....
To be fair, all living creatures are full of bacteria and the such like (including us).
[*]When I was bitten by a dog many years ago, the doctor treating it told me that in her opinion it is bites from other humans that are the worst, and where thh skin is broken infection nearly always follows from a human bite.
[*]Cat bites are way worse than a dog's one too, my poor dad ended up in hospital for several nights, nearly losing his hand, because of a tiny little bite from our cat.
The safest bet is once the skin breaks, treat assuming there is an infection.
