Hi people, new member searching for info and came across this thread. A couple of my girls suddenly have "hunks' missing from their necks. After the info in this thread (thanks) I'm pretty sure it's moulting and nothing more 'sinister'.
A bit of related curiosity on this topic - my question is "why now"? The OP is also in Australia and her initial post was in December which is the middle of summer over here. How come our chooks would start moulting now, rather than in autumn/when it's starting to get cold? It has been blazingly hot lately, I can't imagine why a chicken's biology would tell it to get new feathers?
