All my birds are 16 weeks (and have been vaccinated for Marek's), except for two 13 week old Silkies I acquired about 3 weeks ago. I only quarantined them for two weeks...(I know, I know. Add this to your list of cautionary tales). I figured if I had them in the coop in a separate cage it would be okay. It is SO not okay! So this morning, I found one of my 16 week olds curled up in the corner. She is panting and has leg weakness. She cannot stand & if we touch her legs, she acts as though it hurts. I also found a couple nuggets of BLOOD TINGED POO in the coop. THE BIG KICKER??? The avian vet that I felt happy to have met has left the practice. I have been refered to a practice many miles away, very far. What should I do?????
