I'm having a similar problem with something killing my chickens. Covered enclosure with no visible points of entry by killer. Door on coop but vents are open but not for long as culprit got in there last night. Any help would be appreciated!
Thanks
I am a newbie, so take this with a grain of salt...
You have not given enough information, if you could answer these questions it might be helpful:
- Are all doors / windows / vents covered with fence or hardware cloth? What size are the holes in the fence (i.e. what is the biggest skull that could fit through it) ?
- There are no gaps or areas with missing wire?
- Where wire meets ground, how deep into the ground does the wire go? There's no gap at the bottom? Nothing dug a hole?
- Check where the wire connects to the posts - nothing pushed the wire away? All fasteners are secure? Is there anywhere the wire is loose enought to get a small body through?
- How are you finding the victims? Solid body with throat ripped out, or completely missing with just a few extra feathers and drops of blood on the ground?
- Do you know approximately what time the killings occurred? If you go out early in the morning and find dried blood, it probably happened early in the evening. Fresh (wet) blood would indicate a more recent (early morning) kill.
My (blind) guess would be racoon. My recommendations would be:
(a) Get a trail cam and put it facing the coop. Knowing your enemy is key to defeating it. This will help you figure out bait options and/or times to be extra vigilant.
(b) Get a "have a heart" trap. Set it with one side closed and one side open. Food at the closed end, not on the trigger, but furthest away. This makes the critter have to cross the trigget to get the food. Bait the trap as you see fit. Racoons like marshmallows - be careful, sometimes skunks do too...
Good luck!
