HI!...i just purchased some ancona hens, one hen has huge warts on face,eyes,around beak, she looks sickly too. From what I read it sounds like fowl pox so I need to vacinate all my birds, wellllll I'm not happy about it since I've never done this,dogs,cats, yes...never chickens, I read under the wing....I have a huge box of syringes for dogs/cats....can I use them or is there a different needle for chickens???? These just seem kinda big to be poken into a chickens wing.....I've had chickens most of my life and never had anything like this, now I'll have to vacinate all the new chicks I order from now on, guess it's a good idea anyway. I wonder how many birds a bottle will vacinate, I have somewhere between 25-30 birds. I should have left those birds right there but I just wasn't familiar with the desease. I free range so it probably won't spead very fast since there are no mosquitos and it is spread by blood....I have the sick one confined. I know I need to kill and dispose of her because there is no cure but I can't seem to make myself do it....I would appreciate any info on this. THANKS!
