About a month ago we picked up 2 mature RIR hens to add to our flock of 6 BR & BO's. At first the new RIR's got bullied alot but in the last few weeks we noticed that they were bullying one particular hen that is very calm and gentle. We first noticed she was missing feathers in the tell-tale spot just in front of the tail feathers. One day my wife caught the 2 RIR ganging up on her and they backed her into a corner and went to town yanking feathers. We just assumed they would eventually get the pecking order straightened out and stop the bullying but more recently she has been picked so bar that she is a bit bloody and now the BR hen is missing feathers too. We're very certain its the RIR hens that are doing the bullying as the 2 hens that are plucked keep their distance from the RIR hens and they are timid around them. Do we need to intervene now? Or just let them tough it out? Do blinders cause problems with free-ranging (as in the hens being less wary of predators etc)? Our coop is a bit small for 8 full-size hens (20 sf coop & 40 sf of run) but we let them out as soon as one of us gets home from work. We used to let them free-range all the time until the local hawk population caught on. Egg production is still good. We have a light in the coop from 3am to sun-up and then natural daylight until dusk. We've been getting 6 or 7 eggs per day (reliably) for a couple weeks now that the new RIR's got settled in and the pecking order is mostly figured out.
