I have a hen who aspirated while receiving vitamins through a syringe (no needle) for the treatment of a deficiency. She is no longer vitamin deficient, but she wheezes and breathes with her beak open. I think she has developed pneumonia. I have Tylan 50 injectable. -Where do I inject her? (I've heard many varying opinions and would like answers from people with experience) -What guage needle should I use? -How much does a silkie hen need? (I've read 1/4 cc but wanted to be sure) -How many days and at what frequency should I inject the medicine? (I've read twice a day for five days but, again, I want to be sure) Thank you!
