I have four khaki campbell and two silver appleyards that are less than a year old and I was gettin four to six eggs a day this fall and it has since fallen off to 1-2 eggs a day with no additional light. When my chickens were less than a year old, their first winter would give me about four eggs for six girls. They are gettin just standard duck pellet mix and red wigglers when I open up the compost pile for em. I thought that since ducks take the winter for well for me that their production would be similar as the first year chickens for me. So far this experiement hasn't worked out as planned.
