Dorkings are not heavy layers. They tend to be seasonal. They go broody easily and they don't lay when they are brooding. They are a great farm bird and forage well, but you aren't going to get the number of eggs that you get from any breed developed to be a laying hen.
Some of the Dorking breeders have increased laying as one of their goals. Any Dorking will give you more than enough eggs to raise all the fryers that you want, but 150 eggs a year would be considered very generous. You might not get any eggs at all in the fall and winter.
