My 3 year old light sussex hen looked very gloomy when i went in. She was standing beside the water bowl, with her crop resting on the rim. I looked below, and i saw the problem. I put my hand on her back and she slowly walked away, which is unusual, for her whole life ( born here ) she never liked being touched, or even people coming near her. She would always run away. I brought her inside, and tried to "remove" the problem, it wasnt going anywhere. I tried hot water aswell but that didnt do anything. So i cut off the problematic feathers, and wiped with some wet tissues. I put her in a nest box, she stayed standing, still looking unhappy. What should i do?
