My girls have some sort of a respiratory illness- symptoms-one with a barky type cough and the other with a runny nose and taking breaths with an open mouth from time to time but no noticeable wheezing or rattling. One of my other girls died yesterday- she was the worst off with labored breathing and wheezing/rattling. I had treated them before with Duramycin 10 in the water but since since the sudden onset again and one girl dying yesterday I went and bought Tylan 50 inject able- all my tractor supply had was 20g 1/2 needles which seem so big for my girls who are only about 4 months old. My question is: can I give it to them by way of soaking the dose in bread and having them eat it? I know I should give it to them by shot but I have a needle phobic husband and he has gotten me so anxious about this that I will try any other way but shot right now. Thank you for your advice.
