Theoretically: My friend found a brown finch in the middle of a dirt road, totally blind with it's eyes swollen and crusted shut. She pulled her car over, got out and picked the bird up. It had no idea she was even there until she touched it. She brought it home, and called me, since I have chickens.... and finches and chickens are practically the same... .... anyway, I told her to use terramycin on it's eyes, which is what I used when my duck had a crusty eye, and when my dog had a pinkeye sort of thing.... besides the law stuff, (i told her she shouldn't have even touched it, but she refused to just leave it...) what else should she know? She plans on keeping it until it's eyes are better, and then letting it go again.... is that a good plan? She said it's a finch or a sparrow, i honestly can't tell the difference. it's got kind of purple/brown feet though... she didn't take any photos, but she said its eyes are totally shut... she's working to get it to eat and drink. I told her to wash her hands like mad. I don't think I want it anywhere near my chickens, so I don't know if I'm even going to see it in person... but do you guys have any advice?
