My 2 year old Rhode Island Red has just finished moulting and almost every morning when she jumps out of the henhouse she flutters around in circles and turns her head under her, closes her eyes and falls down on the ground. After lying motionless for a few seconds she jumps up as if nothing happened and goes about eating and scratching the dirt as usual. This has been going on for a couple of weeks and I am concerned for her as the other hens want to attack her when it happens. Please let me know if anyone out there has experienced this behavior?????
