This pullet is listless and seems weak. She won't really walk. I stood her up and she hobbled a couple steps and plopped back down. Not interested in food or water. I put some watermelon in front of her and she wouldn't touch it. Whatever it is, I lost a 22-week-old rooster to it also, a few weeks ago. He acted the same way. I noticed it one day, he was dead the next morning. I expect this girl to have passed by morning. I'm not sure how old this girl is, but is not laying age. Any thoughts? Some in my area have mentioned Marek's.
