My FBCM all about a year old and my Ameraucana who already went though molt and my Brahma mix (7 birds total) have all but completely stopped laying, well actually I am pretty darn sure that only one chicken either my only blue or a black Maran is laying. It has been this way for well over a week although it dropped off slowly. I checked for mites, the roo had some a few weeks ago around his vent and I dusted them all with an organic dust which has never bothered my birds before. There are no mites around the vents of the girls at all, infact they are very clean. They are all a good weight nice and meatie but not fat. They have had the same light set up all winter and have been fine about 13 hours on. None seem sick in any way at all and they are not hiding eggs as I looked everywhere in the coop and run. I am out of ideas and have orders to fill. I put some organic Cayanne powder in their feed a few days ago and still just one egg today. any ideas?
