Some will, a lot won't survive. Egg production will be down, and non existent part of the year. A lot depends on the land, some land is capable of producing a great deal, other land not so much. People talk about bugs, but unless you are raising the bugs in an artificial environment, bug are only a couple of months out of the year food.
Personally, I live on a praise with more acres, but if mine range too far, predators get them. I have numerous wild berry bushes, but predators are there too. I have found a slight reduction in feed durning the months of June and July, by mid August, the population is in decline, to end abruptly in the first hard frost.
I like a food garden for ME, not the birds so much, they get scraps.
