I didnt have such good luck with my adopted GLW hen. She is 1 1/2 yrs old & extremely aggressive towards all the other birds. Actually terrorizing 2 particular hens. One being a RIR & a Jersey Giant. She isnt mean to humans, just other chickens. She actually seeks out the two I mentioned from across the yard and comes charging after them. Jumping on thier backs, pinning them down & ripping feathers out of tier heads. Just an absolute terror for my other hens. I have 7 total. I had to remove her from the rest & place her in a large dog cage for now. I might re-introduce them in about a wk & see if the pecking order has knocked her off her edistal a little bit. If not, shes going to a new home. I also had a SLW I got at the same time I got my GLW#. They came from the same flock. The SLW was extremely antisocial & aggressive towards my smaller RIR & Leghorn. From my personal experience, I do not recommend Wyondottes if you want a docile sweet flock without bloodshed. Thank you! (Also, if anyone has any suggestions & can get back to me asap please do. We love Phoenix, but we just cant have such a mean bird in our flock). Today is 7-12-14. I will re-introduce her back into the flock in a week. Shes got a wk to straighten up her attitude. I hope she does!
