My 23 week old pullet started acting strange this afternoon. I noticed when I let them out to freerange she just stood in a corner, she's drowsy...no energy. Comb and wattles are somewhat pale, one eye closed, when it did open it was watery but no goop or drainage. Crop is full and greainy. She started laying a couple weeks ago, laid a normal egg this morning. She is on layena crumbles I mix de with it, acv in water. Honestly I have not seen her eat or drink today, giving her some yogurt now which she is taking. I have not noticed her poo but am keeping an eye out. Does she need antibiotics? Not sure what to do, she is my favorite chicky and all the others seem fine...PLEASE HELP THANK YOU!
