Totally devastated, never had this much grief since a member of my family past away. Even though they had only been a part of my life for 1 month, I really bonded with them and they would all cuddle up to me and peep loudly when I left them 3 days after moving them into the coop which was very secure with extra high grade welded mesh and the unit placed on concrete foundation to prevent predators digging under. I had unfortunately let one thing pass which I wouldn't have thought a fox would do in a million years. My coop had a pull out tray to make cleaning easier, the fox pulled this out with its teeth! In the morning I had discovered teeth punctures and scratch marks with the tray on the floor and evidence of a few chick feathers.. Warning to you guys if you have this kind of tray system coop - please secure with door bolts and padlocks. I now have realised how sly and cunning foxes can be, the tray wasn't even protruding and completely level with the back of the coop. Lost for words..
