How to deal with an agressive hen

[Nik-T]

Our hens at 3 months old have currently stoped laying due to the winter months and the cold weather. But I thought they have started to molt their feathers as their are feathers all over the cage. Just suddenly yesterday I noticed one of our quails had blood above their beak and started to wonder what was happening. It appears one of the hens have become aggressive and she spooked the other 6 quail hens who tend to jump crazily. I'm worried one of them might break their leg due to the space above. Already we had one quail brake their leg to high jumping who has now recovered but i dont want any more injuries. Just wanted to attach a photo of the quail that had been injured, i wonder if i should separate the aggressive hen to keep the rest calm as I do no want any others to be injured or worst scenario for her to kill one of them

Sounds like you need to separate it.

I would separate your bully for a day or two and then put her back in to see if she has learned her lesson. If she has, great, if not, then you will want to think about culling or rehoming her.

That injury looks like it could be a puncture from wire or it could be a rat bite. I would double check to make sure you don't have rats or mice coming in. Those can also spook your hens.
