I am having quite the interesting dilemma with my flock of 16 hens and 2 roosters. We were getting 6-12 eggs per day, even through weeks of negative double digit temperature. On Monday, I gathered 9 eggs. No eggs on Tuesday. I let them out on Wednesday (I let them out around noon on nice days) and left the coop door open overnight; something I do quite a bit and have never had any problems. No eggs on Wednesday. On Thursday I put up a trail cam hoping to catch the culprit, and locked the chickens in. No eggs on Thursday. This morning I checked the trail cam; nothing. No eggs on Friday. This evening I set the trail cam up and baited it with three eggs. I had to buy the eggs...
There is absolutely NO trace of four days worth of eggs; no wet bedding in the nest boxes, no shell shards.
I see no abundance of feathers, and have no reason to think they're molting. They are all a year old.
They have free access to fresh water, layer feed crumbles and pellets, oyster shells and grit. They also get about 3 cups of scratch each day. On days when it's 20 degrees or colder, they get hot mash (their feed and some scratch.) They also get scraps; fruits, veggies, bread. None of this diet has changed; not even the brand.
I did clean the coop on Monday, but they are all friendly and are used to me cleaning the coop. I used the same softwood pellets for the floor and the same pine shavings for the nest boxes. None of this bedding has changed; not even the brand.
They have supplemental heat lamps on an automatic thermal indicator that turns them on at 15 degrees.
As for danger to chickens and eggs wildlife up here, we have bobcats, coyotes, fox, raccoons, opossums, weasels and skunks. All reptiles are still in hibernation.
I am completely at a loss here. No idea what is going on.
Any ideas or help would be greatly appreciated. I love my chickens, and I want to find out what's wrong
