We just introduced two 2 month old hens to our two 3 month old hens, none took a liking to one of the new ones. She stayed away from the others and was a bit lethargic, I thought her lethargy was just due to the girls establishing a heirarchy and getting settled, but lately she is getting worse. The others do not peck at her, but she lays down a lot and pecks at grass and doesn't walk around with the others. I've also noticed for about a week her poop is pinkish--not bloody-- but looks as if it is tissuey and is smells terrible! I thought she was just adjusting to the new food/surroundings but I'm getting worried. Anyone have any advice? Thank you!
