Hello! So I have been noticing one of my chickens has been looking a little scruffy but didn't really think much of it. However, today I went out and another chicken (Speckles) started pecking at her feathers. Then Speckles went over to a third chicken and pulled out and ATE some of her feathers. What is going on here? They have been stuck inside because of snow and cold temperatures, so are they bored? Do they need something (protein, calcium ext.)? Is it a pecking order problem?
