I have a flock of five hens: one EE, one silver cuckoo marans, and three red stars. They are all one year old, and have all been laying for a while now (the EE started a few weeks ago). Just this week we stopped getting eggs. I noticed that all of the hens but the EE appear to have had all of the feathers ripped off of their butts (right below their vents - kind of between their legs), so I assume that the EE is pecking the rest of them (we have seen the EE pecking the others). Could this be what is causing none of them to lay eggs??? How do I fix this? PLEASE HELP!
