I have a hen that had some sort of sickness last week, not sure what it was. She was lethargic, not eating or drinking, and had yellowish-white runny poo with dark green chunks in it. Not good. I took her out of the flock and put her in a separate pen by herself so she couldn't infect the other birds. I called a few vet offices to find out if I could get her poo tested for worms, but vets won't do anything for chickens around here, grrrrr.... The only thing I could think to do for her was give her some antibiotic powder in her water, which I did for about 4 days. Gave it to her 3x per day by syringe. Now, she is eating and drinking fine, active, and her poo is looking more normal. Not 100% normal, but much better. What I'm wondering is how long should I keep her away from the other girls? It wouldn't be such a big deal, except I'm leaving on vacation next Tuesday and won't be back for a week. My neighbor is taking care of the chicks while I'm gone. I would hate for them all to get sick while I'm away. What would you do??
