This is a flock of 5 middle aged (2+ yr old) hens that I inherited from a neighbor who moved away in July. I had been taking care of them before they moved to my place, and they were laying 2-3 eggs per day. That slowed down quite a bit after the move but had recovered, and by August they were back up to their previous level for a month or more. Then we had the rains/floods a few weeks ago (the floods in the news in Boulder and elsewhere in Colorado). We did not have any flood damage, thankfully, but the chicken run area had 1-2" of water running through it over the ground for 8-10 days (normally bone dry), and it was cold and wet for a week. The girls made it through the rain, but I could tell they weren't happy to be wading through a "stream." Their coop was dry (up on stilts 3'), but the rain and water on the ground made for a very cold wet week or so. Since that event, their laying has tapered off, to almost nothing. I am continuing to feed them layer feed, and occasional garden extras, but they just aren't laying eggs. I sometimes see one of the hens in the nesting boxes, but no eggs get left there. And I have not found any other eggs hidden around. For a while it was one egg a day, then one every other day, and so far this week none. I have noticed that they seem to be eating less of their feed than before too (it is available all the time so the decline is their choice). Otherwise the hens seems fine, are active, going after bugs in their yard, and come running for scratch and extras when I come over. So I am not sure what, if anything, I could or should be doing about this. Is it just the trauma of a week of cold wet weather that has shocked them into not laying? Could there be something else wrong that needs attention? Thoughts, suggestions?
