i put my 6 week olds in with my 10 week olds in the coop yesterday. thismorning i came out and one of my 10week olds was dead. the 6 week olds had peaked it to death! i was so freakd out! i didnt know they would do this... it was penny that died. i have buket nest boxes and and they all try and pile in to one.. but poor penny whent in with the 6 week olds and they killed her. this sucks. i seperated them.. but im afraid to put them back together.. and im getting a hen tomorow.. i dont want this to happen to her too.
