I was given 15 hens. Some old some in between and some young. I'm trying to think of a way to figure out which ones are laying and which ones are not. I know how to tell if a hen is to young to lay but idk how to tell if a hen is finished laying. Other than the obvious no egg. I was thinking about taking each hen and putting them in a big doggy crate and leaving her in there a couple days. No egg = she's finished laying. How long should I wait before I can say she's not gonna lay? Will this work you think? Any other proven ways?
