Most of my chickens are fine now. A few are still a little sick, but much better than before. I lost 2 to the illness before I finally got some antibiotics. I reccomend getting some from chewy.com. They can be mixed with water and given directly to any sick chickens if you use a condiment bottle. My prolapsed hen is doing better, but her butt is still healing. She's still getting antibiotics and quarantined in a cage until her butt heals. My babies are doing well since they got antibiotics early. You can give them the antibiotics by squirting the water into their beaks. You'll probably need to hold them down, pry their beaks open, and squirt it into their beaks before they start struggling and escape. Some are better about getting medicine than others. Some of mine are fairly cooperative, while others struggle and kick. You could also just put it in their water dish, but you'd need a lot of antibiotics since it's made for smaller birds and the largest size is 3 ounces. That's why I reccomend the condiment bottles. It takes much less medicine, and you can ensure that the sick chickens are getting what they need.
