Need help please....i have 2 hens in particular who are sisters, last week one of them took herself from the rest of the hens and spent most of the time huddle in a corner or facing the wall. She didn't and only drank when i took it to her. Her sister kept on attacking her whenever she came into her view and i had to confine her so she was safe. We thought we were going to loose her but she's fine now and seems to be back to normal. The other chick still keeps trying to have a go at her but either the other one retalliates or 2 of my other hens intervene, bless them They seem to have,been protecting her since last week. Just wondered if anyone had come accross this type of thing before?
