I have a 6 month old bantam marans pullet who needs urgent help. She has not eaten in appx 4 days, nor has she laid an egg in 6 days (she usually lays everyday). I have checked for prolapse and see no symptoms. She is acting very lethargic. Hangs out in the corner of her coop and will rarely come out. She is housed alone, in a 3'x3' wood coop and free ranged during the day with the rest of my flock, who are all acting normally. Poop appears normal in color and consistency, although the quantity is diminished (likely due to lack of food intake). I have checked for signs of problems with her crop, but it feels, looks, and smells just fine. Wattles are also full and red. Any ideas? I'm very worried!
