Ok, no wonder she is having a hard time. That is "Bumblefoot" infection, caused by a staph bacteria that invaded a break in the skin. Her immune system is overloaded, with bumblefoot infection and the upper respiratory. To have it on one foot is not good, but on both. Double trouble!
Oh well, you've got some more doctoring to do.
- You need to soak her feet in a warm solution of Epsom Salt if you have it, if not use some dish detergent. About 5 min will do, just need to soften and clean those infections. Dry thoroughly.
- Next, a thick coat of Neosporin, I prefer Colloidal Silver, then cover with a band aid or gauze, then wrap the foot with some self stick gauze to hold and protect everything.
Many people use an exacto knife to cut out the scab/infection plug first. But, it is small, so I think for today you can get away with a conservative approach. You can take another look at it tomorrow and see if you need to get more aggresive.
I don't have any experience with Tylan 50, only use Enrofloxacin. So, I do not know if it will have any affect on the Bubblefoot. But, the topical antibiotic should help. Dressing needs to be changed every other day the first week. Then, if there is improvement, every 3 days till healed. She must have cut her feet on something outside and it got infected. May want to do a foot check on the rest of the girls. Some chickens just have sensitive feet. My rooster has to wear shoes to keep his feet in good shape. He had a really bad Bumblefoot at one time.
Yes, her eye is still inflamed., the sinus on that side is inflamed and causing her eye to be irritated. Apply a warm moist compress if she'll let you. Keep using the Vet Rx. Poor baby.
If she will eat to keep her strength up she might make it. Lots of TLC, and loving voice from you will also help her spirit! The feeling of being cared for and loved, gives a huge boost, even for animals.
Right now, she is in critical condition. But, each day that she eats and drinks will bring her closer to a healing!
God Bless...praying for you and your little one.
