I went from getting around 6 eggs per day to getting one if I am lucky for the last couple of weeks. I have a total of 9 hens that should be laying. 3 of them are molting hard right now (along with my main roo) Here are some details about what has been going on, let me know if any of this could be a cause to stop laying: 1. I sold 5 hens that had been with the flock awhile about a month ago. 2. I switched their coop bedding from pine shavings to sand about 3 weeks ago. 3. The weather just turned quite cold. 4. About a month ago I introduced some new pullets and 2 cockerels I hatched in the spring. 5. I just switched their feed from normal dry grains to fermenting their feed. 6. 3 hens and one rooster are molting. My husband and I have scoured their yard for a hidden stash multiple times and found not a single egg. I don't understand that technically 6 girls should be laying, but they just all seemed to stop at the same time. It was around the time the other hens started molting, but why would it impact everyone? I also have not seen the roosters mating the ladies at all lately, which is very unusual, although I suppose the Roos know the girls aren't laying? Please help; I am getting worried!
