My Heritage "pure standard" breeds are my best broody's.I just got done dunking a whole bunch of Dorking Austrolorp and GLW in water and chucking them in rabbit cages. 6 of them had a zero percent success rate. They are broody, but not broody enough to actually hatch eggs. Just enough to be annoying. Compared to my games that have had a near %100 success rate. Had some flooding is the only problem the games have had, but the one that lost a clutch is back on eggs. Never again on the crappy "heritage" breed broody hens, but that is what I said last time.
