Bullying Chicken!

[frogga]

One of the 4 girls we have has become very aggressive towards the other 3 lately, pecking, stopping them from eating/drinking, however only when in the run, when in the garden they are all best friends. How can this be stopped, I had to use the hose to get it out the run this evening to allow the other 3 food and stop its viciousness towards the others.

I feel pretty bad as it got pretty wet, does anyone else have this problem and can it be solved in a nicer way

How long have you had them? How big is your run and how long are they kept in there for?
Have you checked for mites or Lice?

Had them nearly 9 months, will check for lice and mites today and treat if needed.
