I want to be humane about things, but, I also am not certain that loss of one eye is grounds for merciful killing. To me it looks pretty bad, but, I am inexperienced. I found some signs of some respiratory infection, in a few of the pullets in this batch, on Tuesday, this week. So, I've been treating with an appropriate level of Tylan 50, since. The rest of them seem to be improving, rapidly. This morning. I saw this, and I'm just not sure what to do. I have Penicillin and Tylan 50 available. The water is still being treated with Tylan 50. Can I inject a youngster, like this? If so, how much? I have various sized syringes and needles, that could do the job. I just don't want to give this one too much medicine. Should I keep this one isolated, with heavier doses of Tylan? Or, is the humane thing, to just put her (assuming this is a girl) down? Please guide me.
