Hi all. I have my silkies in their run most of the day. It is completely surrounded by 1/2 hardware cloth...seems very secure to me. I'm wondering if Hawks could reach their talons in & kill a chicken. I'm asking because on two separate occasions, a saw a hawk on the ground going around & around the run tormenting my chicks. They are 6 weeks old & they don't have any older hens to "teach" them to maybe run into the coop if they are feeling threatened. Should I worry? Thanks!!
