My astrolop hen Sweetie was laying on the ground this morning, she had just laid an egg (out of the nesting box, which is unusual for her) and she didnt stand up when I came by to check on her. When I picked her up she was making a gurgling sound. I brought her inside and she is sitting in a box next to me. Any ideas on what I can do to help her? She is moving her head at odd angles, and keeping her mouth wide open. She was 100% fine yesterday morning, all the other chickens are fine. We havent had any new chickens come onto the property since last august and those were hatchery chicks. Any help would be appreciated!!!!
