Well, Im really excited for you..I would love to see some pictures of them when you get them going..You just have to wonder if they might be from those origional birds
I know I have posted this befor , but the story I read on an Australian site a long time ago was Some people in Australia were trying to bring thier record egg layers back home to Australia from America ..But no one knew exactly where they went outside of Mass and Calif...Somone in those 2 places with very deep pockets bought the record egg layers when they were setting records long time ago , and that parent flock and brought them here..It was a little competative thing..east coast west coast thing..Then when people stared moving into industrial revolution and away from farming..they dissappeared ..no one can tell anything more than they were absorbed into different flocks and even a bit of them in hatchery birds...We tried to find that site again, but were told over time people lost interest so It was deleted..Otherwise I would post it again for you,,It was interesting.
One of the reasons Queesnland held out for the tighter feather was they are known to be much better egg layers than the poofier birds like Orps..They were OK with the deeper shape but absolutle NO to the loose orp type feather.
There was a guy on that site called himself "ancient australorp" If you wanted to know anything about australorp , he knew it..
