Chicken poop normal?

[Bawkbok]

New chickens absolutely create stress - for all involved. If she is on the lower end of the pecking order, this could exacerbate her stress level. With each new introduction, the pecking order has to be re-established. If there is a large difference in age - you may find individual mini flocks based on ages. We are going through this ourselves with recent additions. Poops in our initial clan became runny and still are from time to time. If all are acting, eating and drinking as normal, then it should all fix itself in a few weeks once the order is established. At least, that's my thinking. Others with more experience than me can chime in and offer better suggestions / advice.
