ISA brown egg numbers

[birdmandan]

I'm sure we've all heard that ISA browns can lay +300 eggs in the first year. But, in backyard environment, how many eggs will an ISA brown lay in the second and third year? Thanks in advance.

Generally about 250 second year, and they tend to drop off very sharply during third year due to reproductive issues. I don't think I've ever had one make it to four years of age.

Thanks for the info. It's almost winter here so things are slowing down. I just picked up 5 rescued hens. They are 12-18 months old. So I can expect at least an egg every second day.

If you do want the egg numbers I described, you'll have to provide light over the winter. I generally don't (due to laziness on my part) and get very few eggs over the winter. I get a huge boom during the spring, though.
