I have a mixed flock - Some chickens are +3 years old, some are in their second year, and about 7 will be laying their first eggs in November. My issue is that being it's a mixed flock, I'm unsure how to tell which hens have laid their last egg (and therefore have the uneviable position of becoming stock for soups and stews. I am attached to all my chickens, but I can see spending money on feed if they are not producing anymore - AND making them go through a strong Minnesota winter as they age. So, other than spending all day watching them, does anyone have a good process for identifying which chickens are and are not laying eggs? I know the 5-6 chickens which are suspect for not laying any more, but need help with a good process. Thanks!
