I can't figure out what's going on! Three weeks ago my 45ish hens were giving me about 30 eggs a day. These last two weeks I have been getting less than 24 a day and today I got 17! What is going on?? 30 of these hens were born in the spring so it's not an issue of molting (I wouldn't think or being too old). They have a light on to make up for when we don't have enough day light. Nothing is eating my eggs either. I am making sure they have enough water and food. The only possible issue could be when we had terrible weather for about 4 days I closed up the barn but they have a window in there. Could it have been too dark that it messed up their cycle? Any ideas what is causing my problem?
