It is good to hear from you!Hi Ron,
it's late I know, but just thought I'd mention that it's believed that, along with a fair bit of Langshan, some Leghorn was probably/possibly added to the original Orp. to create the egg-laying machines that achieved world-wide fame. Not saying it's come from your end. The white feathers in young BA's might be a hint!
Cheers Geoff
The Australorps that come from our Hatcheries have more recent crosses to Leghorn. The hatcheries try to make them more easily feather sexed as well as increasing their lay rate. Still not as bad a lot of breeds though.
