I noticed my hens were snicking about a month ago. I hoped that it was just pollen or dust messing with em but they are still doing it. At the 1st they were all regrowing feathers and their combs and wattles were very pale their feathers are all grown in now and their combs and wattles are improving but the egg production is starting to decline and the snicking is still going on. Through all this they have been very lively and curious and seem to be otherwise happy. Today I got an egg that was almost white with very little brown on it. It's rough to the touch and has a hole in it. As I mentioned before they are all snicking or coughing but very lively and seem happy. I'm worried about them and don't really know what I should do. Any help would be great. Thanks in advance for your time.
