We had 3 baby chicks hatch out the day before yesterday and yesterday I was on my way back to check on them at the coup. I heard one of them crying so I hurried back as fast as I could to see what was wrong. When I got in there I saw two mama hens pecking at a lil chick and I hurridly grabbed the hens and tossed them out of the coup and I grabbed all three babies before they were all killed (all thought the one was only hurt but it turned out to be dead). I cried so hard and was furious. I don't know what happened because the hens werent being aggressive before. We guess that three hens each hatched out one chick and the chicks wanted to be together so they kept switching mommy's and the mommy's didnt like that. I am so mad and feel so awful for the one chick. But I have taken the chicks from the hens and raising them myself so they wont die too.
