Question- I have about 100 chickens in summer I sell 50 or so doz a week , I feed them 40 lbs food a day- 17% protein- since it got colder I am lucky I get 2 eggs a day!!
is this normal ? I cheat them with the light now too.....
it's normal for egg production to slow/stop during winter due to the shorter days and cooler weather, also depending on age molting is normal around this time of year.
but a quick head crunch of your numbers (if all 100 of your chickens are hens) seams you're not getting the best egg production even in the summer and feed conversion is horrible, what are their age and what breeds are you keeping? there are breeds with much better feed conversion that will lay 6-7 eggs per hen per week even during winter.
