I am looking for a good solution to identifying my sets. I did 8 incubations over this year and now have a laying flock of my project breed. Next year, I will want to cull those pullets at or under 1 year old, with the oldest birds being culled first. I have not yet tagged these birds in any way, but I will soon cull my original layers leaving me with nothing but project birds, whom I will want to tag to differentiate them from Generation 2 birds. And tagging based on settings would be preferable also. I bought some leg rings, but found they weren't the right size (too small), and extremely difficult to put on. I am alone, so trying to hold a bird and tag it is challenging. I take birds from my brooder, move them into a juvenile run, and then into my main flock. The settings are at least 24 days apart, so there is a noticeable difference in size when I move them from the juvenile run to the main flock. That is where I expect to tag them. They are typically 12-14 weeks old at that point, and again, won't stay there for much more than a year total. What is your preferred tagging method, with a link to a product would be even better. FWIW, my project breed is a cross between BCM and (gen 0) Red Sexlink/BCM crosses. They are not small birds, with pullets typically being 6-8lbs at 6 months. Oh, and I only need to tag pullets.
