i have lost 2 chicks in the last two nights. yesterday i couldn't figure out what had been able to reach though the fence and pull a chick partially threw and only eat the head and upper body. i thought it could be a cat or weasel, but this is a 8x8 pen with chicken wire on all sides and the top. early this morning around 3 am, i looked out the window and there was a owl sitting beside the pen. this morning when i went out one of my buff chicks was dead in the same way. i have seen the owl swoop down at the at night before but i didn't think anything about it. it must swoop down and get the chicks panicked and just wait till one tries to go threw one of the holes and then grabs it. is there some other way to stop this from happening other than killing the owl? my usual guard dog is sick and not able to do her job and it is taking its toll on my flock. please help.
