You just confirmed what I was thinking I should be doing, locking my hens in their coop/run for a while. I am having issues with missing eggs. We have 17, 14mo/old, hens and a coop with 6 nest boxes. I had noticed a decrease in the eggs I was collecting form the nest boxes several weeks ago. I thought that maybe with the heat, they were slowing their egg production a bit. But then, last week, we discovered an egg stash in the center of some 4ft tall ornamental grass. I caught one of our hens going in there. That's the only reason I found it. There were 11 eggs in that grass. Three I threw away because they wanted to float in water. Well..I usually collect about 14-15 eggs a day. I'm now down to 5-8! I have looked everywhere I can in and around our back yard and all around the house in our flower beds/under shrubs. I have even gone as far as searching the woods next to the coop in our back yard. They are filled with poison ivy and I am extremely allergic, so that is how desperate I am to find out where they are laying. I had also found a 4-5ft black snake in the nest box area, twice last week and the Thursday before that. I carried it away, but it could be coming back for a snack. But somehow, I don't think it would be consuming all of the missing eggs in one meal. The snake I found didn't have any visible lumps in its middle. It seemed cold and slow. I am missing all of the smaller eggs that our Dominiques lay and a few of the large Orpington eggs. We are also having issues with feather picking on the hen's backs, and last night when I was picking up the balding chickens, I found that they were missing feathers on their abdomens, to either side of their keel bones and up under their wings. I am going to dust for mites/lice. I guess that I will go to the Disease part of this forum to ask their advice for that treatment. We have lots of wild birds that are always in and around the run. I read that chickens can pick up a different kind of mite from wild birds that is harder to eradicate. Figures! I don't know why, but I thought that keeping chickens would be a heck of a lot easier than it's turning out to be!
