Yellow Mucus discharge from eyes and rattling breathing

This morning I had two of my older girls down with rattling breathing and one of them had eyes glued shut with a yellow mucus. I got her and opened the eye and yellow ooze squirted out all over my hand. She was in miserable condition as she did not even object to any of this. I read a few older threads that reference using Tylan to treat this type of thing, but want to ask and see if any of you have had more recent interactions with this type of thing and make sure I am doing the right thing. Taking them to the vet is not really possible as they cannot see my girls until Monday and I do not want to wait it out until then as I feel it will be late for them. TSC has the Tylan in stock and I am wondering if I should just get it and try it on them. I also have some vet eye cream that I used on our cat to treat a greenish mucus infection in his eyes when he was a kitten. I will be using that on them both after I get home from work today. I hated to leave them this morning but I had to go to work. I am hoping t hat someone can help me with suggestions this morning on a course of action to cover this weekend. Any thoughts are appreciated.

using the tylan should work to clear up her eyes

Thanks, I am lucky I guess, been having these chickens for almost 4 years and this is the first issue I have had. I think it came in with the 4 new adolescents I got from a "Trusted Breeder" in my area that I have known for years. I kept them apart for a couple of weeks and they seemed fine. Those girls are all fine, I assume that one or more of them is a carrier of something. Should I give everyone a dose of this or just the sick girls for now. I only have 7 total now as I had a neighborhood dog visit me about a month ago when I was at work and killed 6 of my girls while using them for playtoys. None were eaten, only shaken to death and left around the yard. I can only say that he will no longer be doing that... Anyway, thanks again for your reply, I will start them this afternoon when I get home, but could you tell me please should I dose them all with it?

I would separate out the two sick girls and treat just them, unless everyone starts coming down with whatever they have then it would be a waste.

Thanks for the advice, I will do that when I get home. I will update here also.

An update as promised. Everyone has fully recovered now and all eyes and noses are clear!!! The tylan worked wonders and I have been watching them since the three days of treatment I gave them and they are all happy and running the yard again now. None of the others showed any signs of sickness and life is good., I even found a few eggs in the chicken house this past weekend. I destroyed them ad will do so for the next week to make sure no antibiotics are still in their system, Thanks for your advice and I appreciate your willingness to help out. Thanks to all the posters at BYC that had info up about these diseases and conditions. It makes raising and keeping my girls a lot easier.
