I think one of my 12 week old chickens has wry neck. It came on SO quickly =( I am stressing big time. These are my first time chickens. They are my babies and I care for them so much. Please help me! I live in Melbourne, Australia and all threads I have read say to use Polyvisol, which must be an american product because the pharmacy and store I went to have no idea what it is!! What should I use instead? Thankyou for your time to respond.
