Have you got an iPad or iPhone?
I have an app called 'ichickens' and it has a section full of photos of chicken poo ( why are we so obsessed

)
I've checked on it as your piccie looked alarming to me but there are two photos both very similar to yours which say it is normal poo.
If she is well I thinki would just keep an eye on her and once all the girls are settled worm with flubenvet so you can eliminate the likelihood of a worm problem on any further issues.
So where are piccies of your new girls
