Chicken with sinus issue Please dont ignore my post

[barngem]

After reading some old posts I believe my hen has a sinus infection, or at least some sort of blockage. She does not have a runny nose or runny eyes. But she has a bump under her eye kind of at the corner of her beak. It looked as thou it was going to go away for a while and now it is there again. I purchased some tetracycline to treat her with and have read that i should put 1 1/2 tsp in a gallon of water. She has been with the other chickens all along and no one but her has an issue. The first time I noticed it was a few weeks ago and it looked as though it was going away but now its back. I thought at first she might have something lodged in the corner of her beak since the lump is quite hard not soft like something infected. I still am not sure its not. She has been eating and drinking fine, but today she seems out of sort and I need to take some action. Since it started to go away at first I had hoped she would recover from this without any antibiotics but apparently that is not going to happen. I have not checked the vet but I am guessing a vet call will be 100 bucks, which I do not have.

I would like to leave her in with the others since if she had something they could catch they would have by now, but I am wondering how to treat her. Can I put a few drops of the mixture in her mouth? I would not squirt it in but use a dropper. Or can I maybe mix some of the water with the med in it with some yogurt, which I know she will eat up right away.
I really dont want to treat every one and I have considered just seperating her for an hour in the morning since she seems to drink right after she gets off the roost.. I found the dosage on another posting so that was really helpful.
It just seems that there is no way to see to it she gets the correct dosage. Any ideas?

She may have an abscess formed there. I have treated ducks with that condition before- and it can be a very long recovery period. each time I thought I had it beat- it would come back. One of the ducks had antibiotics for 5 months and 3 procedures to drain and scrape the area before he was cured. I hope for your sake your hen is not so hard to treat- or that it is something else causing the lump.

If you put her on an injectable antibiotic, it would be much easier to medicate her without medicating everyone. I have used tylan 50 with good results. I got mine at the feed store.
