I currently have 3 laying hens who have just begun to produce again. 1 of them was really shaking a lot and she seems more uneasy then the rest of them and more than she normally. Today was her 1st day laying after a long time of stopping. She laid an egg and then went inside their chicken house and laid what seemed like egg yolk without the egg shell. There wasn't much on the shavings but yellow running down her leg. Can anybody please help me with her?
