My chickens free range in daytime and are penned at night. Here the last 2 weeks we've had goats in the pen around their coop who were breaking into the coop--so the coop was getting torn up. I have done some repairs, doing more every day. We've had foxes, and they would take 1 at a time, or so, leave feathers, etc. We've had snakes (especially when we had babies). They'd take babies and maybe eggs (not sure), and seemed attracted more to certain breeds (red stars) and were so stupid they'd kill ones too big to eat and then we'd find them all slimy where they spit them up and several little ones missing. We have a pig in the pen around the chickens and guineas out there too now, and haven't seen a snake in a while. This year we've lost a chicken here and there, mostly that didn't go up at night or something. I figured foxes. Babies are on the ground and read to move out to the back of the coop (I put a inner fence there for them, so they can meet the older chickens through the wire, then open the fence one morning. Then the goats tore up the coop and we've lost 6 chickens in 3 days. I know, fix the fence. Working on it. But what's eating them? Here's what's weird...I know snakes will take ceramic eggs. But none of them were taken (we had 11)...until Friday night, when 8 eggs disappeared in one night! Snake party? I'm thinking some animal that stole the eggs for its babies/nest? Would a fox do that? I know a pair had babies out in the woods there last year behind our property and that's when they got greedy, but still only 1 chicken a day. (not acceptable but nothing like the current). What would kill multiple adult chickens, leaving only feathers, and take multiple ceramic eggs in one night?
