Hi I am new to chicken keeping but bought an Igloo hen house suitable for 3 chickens. I susbsequently bought three chickens from the same batch and two of them started laying. They had plenty of room within the hutch, lots of food and water and a good space to wander around in. (20 square meters or so) Unfortunatley within a week one of the chickens had died because her vent had been pecked so much during the night. Then a week later I noticed one of the remaining chickens pecking the other one's feathers and took note but didn't speprate them at that point. I thought they were trying to re-estalish a new pecking order. I went to let them out the next morning to discover that she too had been horrifically injured and immediately removed her from the chicken house. She too subsequently died. I now have one chicken left who is obviously the killer chicken - the question is - will she continue to do this if I get more chickens (and carefully re-introduce her after a period of quarantine so she won't be at the top of the pecking order) - I dont want to risk it again - Can I use one of those things that goes over their beak so she can still feed and drink or is her personality now set? Any help gratefully recieved!
