Thank you for the photo

Do you have someone that can help you? If not, then wrap her in a small towel or even a wash cloth, this way she's not flapping around. She's so small, it would be best if you set up at some place like the kitchen table. Put a layer of paper towels or an old towel down. Lay your chick on that. Flush the eye with saline, you can use a warm compress too. I would not use tweezers either - but use a qtip and begin working that crust and pus out of the eye. Flush generously and get the eye open. Look for any debris or more pus. Remove anything you see. Once the eye is flushed and cleared of pus, dab just a little dot of Neosporin in the eye. Do this atleast 2 times a day. See if that clears it up.
Also in the photo - is does her ear have pus or gunk in it?
