Can anyone help me to understand why would a hen kill a baby chick please? The only other thing that would kill the chicks is ? cat? I have 8 hens and have discovered that one of my hens with chicks has 4 missing one beheaded and another has 3 missing chicks...... they may have squeezed out but surely with all the room in the chicken area they could get away and a hen would leave them alone. The only other thing that may have done this is my cats? I have now locked the whole lot up and can not find the lost babies. I have electric fencing to keep out the fox and even put wire mesh under the baby pens, however one baby got caught so im not sure this is a good idea. I like them to be able to run free but this is getting too hard. Has anyone got any suggestions please.
