I noticed one of my HBG guarding a nest yesterday and it spawned my interest in this thread. ML's GG look almost exactly the same as my GSF/BG hybrids. ML's growth is a little ahead of mine but this is probably in part due to climate differences between Ohio and Texas. It would be interesting to stock both GSF/BG hybrids and GGs in equal numbers in the same pond for comparison. It appears that marking one breed would be a good idea in this type of experiment.
