This might count as a double thread I'm so sorry if it does but Im going to need an answer to my questions before I will attempt to get the injection of it to my mini bantam Penguin. He is on Oxytetracycline powder in his water but I want to give him something that will make him feel better faster. He has some sort of upper respiratory infection/disease and I was told on another post Tylan 50 works wonders. The dosage for him would be 1/4 ml and I was told to get a 22 gauge 3cc syringe. I know to put the needle in sideways just under the skin in the breast muscle, make sure I'm not hitting blood, then slowly inject the antibiotic. I was told once a day for three days to do this. My questions are: 1. Should I take him off the Oxytetracycline when I give him the first shot? 2. Should I wait 12 to 24 hours before giving the next injection? (I know to alternate breasts) 3. And should I be aware of any deadly side affects of this? Should I watch him for a while after I give him an injection to make sure nothing bad happens like a seizure or anything like that or is that something that won't ever happen? Sorry again if this counts as a double post I just need to know! Thanks!
