I've gotten several hens as rescues, and I know some of them are not laying any longer. I have 40 7-week old pullets coming up and I don't need to be feeding those no longer producing. I have 4 Easter Eggers and I get 1 beautiful blue egg from them every 3 or 4 days. I'd like to keep the one(s) laying, but can't afford to keep those that aren't. I found someone to process for me, but want to make sure I don't pick the ones laying. I do have a place to separate, but unsure how long to keep one in there before I decide who is and who isn't laying. I also have 6 barred rocks, I know I'm getting some eggs from them, but again, no idea whose laying. I have 3 young Australorps and 4 older ones. I know the younger ones are laying but unsure of the older ones. So I guess my question is, how long to keep each one separated so I know who is laying and will it stress them out so much they won't lay? I am going to try to catch them on nests and mark them, but again, they could be sitting and not laying. Help!
