We have six chickens of all different breeds and the Silver Laced Wyandotte has been the number one hen (we don't have a rooster) almost from the beginning. The hens are now 10 weeks old and she has been displaying such nasty pecking and attacking behavior that I'm starting to wonder if we have to re-home her. She appears to randomly choose a bird, then runs up and delivers one or two very hard pecks (going by the reaction of the peckee, it must hurt). The other day she did this and pulled two feathers out of the poor victim at the same time. They aren't overcrowded (6 chickens in an 8X6X4 coop with a 12X18 foot run, plus yard time) so I don't understand why her behavior is suddenly so aggressive. Do hens like this ever go back to their own friendly nature or is it likely this bird needs to find a new flock?
