Hi all For the last week our hens have been behaving badly. They go into their nesting box and scratch all their bedding out. They go into the chicken coop and behave erratic and knock down their perches. They jump back down into the run, then as quick as a flash they are back in their coop creating havoc again. One of our hens started this and the other two have followed suit. So we have 3 naughty hens at the moment. They are eating and drinking, although they don't seem so enthusiastic about their treats (potato peelings, rice). Now one of them is behaving lethargic and stands in one spot, quietly, moves a little then stands still again (she did this a month ago and 2 days later was back to normal, after I took advice of giving her more calcium in her diet). Also their egg laying is inconsistent, we have days when we have 0, 1, 2 or 3. Also sometimes the egg shell is unusually pale. They have plenty if grit and we feed them layer pellets, and put cider vinegar in their water. They have also just finished their monthly treatment of Verm-X. Any help you could give would be appreciated.
