One of my hens started off with a watery eye which within a few hours it comoletely closed, I then separated her and brought her inside, the next day it was both eyes, she has stopped eating and drinking so I had to squirt some antibiotic treated water in her mouth. Next day she had a white film over both, I cleaned her eyes out and started giving the rest of my flock antibiotic treated water. She developed a cough and today she doesn't look good. When I went out this morning I noticed that another hen that was in the sick ones coop had a watery eye as well so I just separated her from the rooster they were with. And advice?
Should I just cull both now so there isn't anymore spread? What antibiotic are you using in the water?
It sounds like your hen may have Mycoplasma Gallisepticum. Mycoplasma is contagious and there is no cure. Any chickens that have been exposed (housed) with her are generally considered carriers whether or not they ever show signs of illness. You would need confirmation testing to be sure this is what you are dealing with, but the usual course of action would be to keep a closed flock. (Never sell hatching eggs, chicks, etc.).
Antibiotic treatment will only help with any secondary infections that may occur. You can try treating with Tylan50 or Oxytetracycline. Injectable Tylan 50 dosage is 1 cc or ml per 5 pounds of weight. You can give it orally or as an injection into the breast muscle 1/4 inch deep. It depends on the brand of Oxy that you purchase so follow the package directions on that.
Since you have a second hen that is showing signs of illness. Separate her as well. Make sure they are drinking well and staying hydrated. Continue to flush the eyes and apply the ointment.
Only treat any chickens that show signs of illness.
A lot of people that have flocks with Mycoplasma (confirmed by necropsy/testing) find that Denagard is usually a more effective treatment method. Once symptoms are under control they use a monthly maintenance dosage if needed.
