i'm getting 2 eggs a day from 13 hens, but 5 of them are only just approaching POL, 4 are new in the summer and i don't know their age, and the other 4 are now 2, and laid faithfully straight through last winter, so it's not as bad as it seems.
they do seem confused daylight wise, some days back to the coup at half 2, some days still outside at half 4, when its dark, have to persuade them to go in before reynard appears!
