I have 6 egg layer chickens, fully grown that I no longer need. This will be their 3rd spring so still fairly young.
3 Rhode Island reds
1 Comet
1 Nj Giant
1 Americana
Must be purchased together, comes with coop, egg shelf, straw and whatever corn/layer pellet I have at the time of purchase. They do lay however with the current weather they have been melting and slowly starting to lay again.
For 99.9% of their life they have been fed organic layer feed, no medication. My local tractor supply was out of organic so they are on Pride layer feed.
