Layer Breed (ISA brown) productivity age

[SleepyChickens]

I am planning to adopt some spent hens from a nearby farm. They're isa brown around 2 years old.

Does anybody have experience in raising isa brown or other layer breed more than 2 years old?

I am planning to get about 10 chickens. How many eggs would I get per week from them?

I'd think they'd still be in pretty high production, laying almost everyday.

My Calico Princess is 3.5ish, and she lays every day for short spurts before taking a short break. So kinda a week of constant, week off, week of constant, few days off, one egg, few days off, week constant..... eat.

My Isa Browns just turned 3 last month still lay almost every day
