Evening All,
Well not even 12 hours in their new run and I had an "attack". Not sure if it was a hawk or a fight between two rooster/cockerels but I went to lock up tonight to find a bird dead in the corner of the run.

I drove up, saw a huge pile of feathers in the run near the coop door and thought Oh no, what happened!? Since it was near dark out there I slowly approached the run incase there was something like a raccoon or something similar in there...I looked inside the coop thru the nestbox door and counted everyone - Sizzle Roo, Little Fella the Blue Orp Roo, Stella, Ella, Chickaletta and Henrietta and the New Splash Orp roo. So they were all accounted for. Went into the run, locked up the coop door and found my little blue Frizzled Sizzle Roo in the corner with a huge gash in his chest. Went back to my car to grab a bag from my trunk to remove him. What is kind of leaving me wondering is this...Yes this new run has an open top but it has a couple of pieces of wood across the top to keep all the panels in place. IF it was a hawk attack, wouldn't the hawk have taken this little guy out of the run? Also, he barely had any feathers missing. The feather pile that was left in front of the coop were lighter in color - like Stella's or the new Orp Roo's color. Do you think Hawk or fight with another roo in the run? I'll look everyone over in the morning and see who else is missing feathers or has any injuries but they all looked fine when I peeked in there tonight. If Stella is missing feathers then I'll suspect a hawk attack but if the new Roo is missing a lot then maybe it was a fight between the two in which case he will need to be separated. I can't have him picking on my other two roos in there.
I'm not too upset about this loss because he wasn't the greatest quality sizzle and I was actually contemplating selling him but I hate that I don't have them in my backyard to tell what happened! I'll be placing some chicken wire over the top tomorrow morning just in case.
