I have a female chicken road island red that in the past 2 weeks has taken ill. She is still drinking and eating but won't stand up and is feeling skinny. I have brought her in the house and have been giving her vetrx and poultry boosters and it just doesn't seem to be helping. I put her back outside with her friends ( I have 9 chickens total) and they won't leave her alone they keep pecking at her. So I brought her back in. She just lays down. We believe she's still having bowel movements. We have seen little bits of them not alot although. We was told she possibly has an egg in her that's stuck? Need help. She's about 3 we believe.
