Hi everyone 
I've had my coturnix quail for around a year now - they've all lived very happily together with no fighting or dominance issues. I have 6 females and no males.
About 3 weeks ago they stopped laying (I'm in Australia and we're coming out of winter, which about half of them laid throughout), which surprised me since we're now coming into longer, milder days. At the time I noticed some feathers around the coop so I assumed they'd stopped laying and started moulting.
Today, though, I've realised that about 3-4 of them are missing the feathers on the crowns of their heads - this is where the feathers are coming from around the coop, which makes sense as there were never a huge amount lying around.
Can anyone tell me why they would suddenly start doing this to each other? I've not seen it happen so I don't know if there's one or multiple culprits.
Would this also explain why they've stopped laying at a weird time of year?
I'm attaching some photos - the scalping isn't super severe yet, but without intervention I feel like there's no reason it wouldn't continue.
Thanks for any advice!
