am getting so frusterated, and DH is ready to sell all the hens. I have 4 hens from last year, they are about 18 months old. I also have about 15 pullets that are over eight months old. I have not got an egg for a month. At least. The hens were giving me 1-2 a day up untill a month or so ago, and I had 6 hens then. (One day I got 8 eggs, so I KNOW the pullets layed some.) They stopped laying, and I assumed the hens were molting. Then two hens just up and died one day, I had no idea why. When I picked them up they were crawling with mites. So I treated everyone, and I am getting ready to do it the second time. (it has been about 14 days) NONE of them ever looked sickly at all, and they are very active. We still haven't got even one egg since I treated them. Shouldnt they have layed at least a few by now? They are getting as much food as they will eat. They seem extremely healthy. The weirdest thing it, we just got a trio of ducks, and I got one egg a day from them for the first three days we had them, then nothing. I have had them for a little over a week. I can think of one other cause. I have an egg eating dog, but I have NEVER seen him in the pen since we built it. (they were totally free range for awhile, and I would catch him eating eggs sometimes then) I would think if he was getting in there enough to eat EVERY egg, I would catch him sometimes. I am in and out all day. So I dont know if they are laying, and something is eating them, or if they are not laying at all. I know I should check their vents for color, and I will get back to you later with that. Any ideas?? HELP PLEASE!! I dont want to sell them all!
