I'm just really having bad luck with my birds lately. I had 11 pullets, raising them from 3 weeks old. Within the first week I lost 2 to coccidosis. Thereafter I lost one to a snake, and in the course of two separate nights in their 17th week lost the remaining 8 and a young rooster to what everyone tells me was a raccoon! Since then I have secured the coop to the extent of Fort Knox: Hardware cloth on the windows, eaves and soffitts, stuffed into two holes in the floor (for snakes), leave a light on 24 hrs a day (for possums), padlock the door and laying box lid (for people), lock the chicken door with hook and eye and barricade it with a stick running the width of the coop, the fence is sunk 6" into the ground to prevent digging, and I've nailed carpet tacking around all four walls of the coop, above and below the windows. I've also got motion detector spotlights and a baby monitor. On September 12 I purchased 12 barred rock 20-week-old pullets and 2 days later, I got a 6-month barred rock rooster. Since then, all's been going well, they've been giving me on average 5 eggs a day, and they seem to be very happy. I've had 2 instances of the rooster starting to crow around 2 am and I've run out to check. One time the spotlights were on; another time they were not. Neither time did I see any evidence of anything trying to get at them, but the birds were really worked up. It's been raining cats and dogs today, and in this area that means lakes on the property, almost to the top of my boots, so needless to say, I didn't let them into the run. I just now (3:30 pm) got out to check for eggs and found a hen dead in the laying box. It looks like she was pushed down onto her side since she was laying on her left side on top of a broken egg. I can find no sign of injury on her whatsoever. What could have caused this? Theories will be appreciated.
