Today I went out to feed the chickens and my EE rooster was dead and one EE hen isnt looking so good. Everyone was fine as far as I could tell yesterday. Today she is fluffed up somewhat and has white poop all over the feathers around her vent. She is keeping her mouth open all of the time. She is standing up and walking around, but she wouldnt peck at the food when I dumped it out for them. She made a lot of noise and fought me when I grabbed her to look her over though, so she isnt super lethargic. Everyone else seems fine, except a black silkie pullet who always looks like she is dying, IDK what is up with her, but I have always thought that she was going to be dead the next time I see her and I have had her for three months. There is nothing new introduced to them, not free ranging so it cant be a toxic plant or anything. They have had Sulmet in their water for a week or so now since I added the juvenile pullets in with the older flock so I dont think it could be anything bacterial. The pullets are the only survivors of a cocci outbreak we had that killed 90% of my chickens that were between 1 and 8 weeks old. That was well over a month ago, but I put the Sulmet in the water when I moved them as a preventative. Any idea what it could be? The rooster was 3+ years old, but the hen is only a little over 1 year old. It has been in the high 80's the past week. They have had plenty of water though. I really cant afford to buy any chickens to replace the dying ones, I really got hit hard with the cocci and lost 30+ fancy breed chickens. So if anyone has any ideas what it may be and how to fix it, please let me know.
