Hi! i know i lost several to hawks, caught them in the act. i know ONE roosters was lost to an opossum. but, i've lost many more and sometimes several at one time and there is NO SIGN of the bird, or the predator!! i've been left a handful of feathers, and that's about it! these attacks are happening usually during the day and when i've left. they never occur when i'm home. and they never occur inside the pen or coop. it's always when they are free ranging in the fenced in backyard. super bowl sunday i lost 8! i was gone for 8 hours and so i haven't a clue what got them :-( after super bowl sunday i kept them locked up. last week the roosters flew out and that day the BIGGEST rooster i have ( who was huge) got taken. he left a ton of feathers. this past sunday ( in the 1.5 hrs we were gone), two more went missing :-( so, they're back to being locked up. what does this sound like it is? i have had hawks in the yard for a long time now. but, they haven't been back since they got the last of the chicks :-( needless to say, my bird's days of free ranging is over :-( and now i have to build some sort of enclosed run instead of just letting them hang in out in their pen. :-( thank you!
