Two advantages and disadvantages of flock mating?

Answer 1

I got my last answer from faulty sources, here’s an updated answer,

Disadvantages,

over-mating is a common problem and can occur if mating is let out of control, this can lead to less fertility as a long term effect

age controlled breeding is vital to have welfare in the flock, failing to control this can lead to less fertility, floor eggs, and an overall decrease in health

Advantages,

Less cost, less time consumption

Flock mating will effectively bring you more eggs than unpopular methods
