I purchased 12 chicks in April, and we've already lost 8!!!!! We recently got 7 more, but I was totally distraught when I went out this morning and saw the remains of my silkie bantam hen all over the yard . There was even a trail of intestines leading out of the coop and a whole wing . My dad and I built the coop together, and we decided to use horse fence intend of chicken wire. It has holes about 1.5" by 3". But, looking at the "trail" it looks as though she simply went through e fence. We completely enclosed the entire run, from ground to ceiling. Is there any predator that could fit through a hole that small and rip up the hen to fit her out? We've looked, and I can't find any openings in the fencing. Grrr ! I know we have : raccoons, cats, opossums, groundhogs, skunks, snakes, and rats. Thank u so much.
