Hi everyone. I've really tried to avoid starting another 'hen not laying' thread, but this case is pretty strange. I got 6 hens in June (southern hemisphere, so June was the beginning of winter) and none were laying. By the end of August they had started to lay, and I've since added 3 more hens who are all laying. However, one of the original ones from June still hasn't laid any eggs at all. At first I thought she was moutling, but then I figured the missing feathers on her neck were due to the rooster. She walks normally, eats and drinks well, is very active and looks upright and healthy. And yet, to my knowledge, she's never laid an egg. I don't think she's an internal layer and she's not malnourished. They all came with leg mites, but that's been treated. I've just bought a levamisole worm treatment, but there's no sign of worms in the poop or anything. I'll give them the levamisole, just in case. What else can stop an otherwise healthy hen from laying? (It's been 6 months now, but the first month was mid-winter so really 5 months of not laying.) Thanks for your help.
