They sold me this huge male thinking it was a female. I don't have any females and doesn't looks like the last 10 robinae at the LFS are female either.
All 10 males defies the odds but it happens. I would give the group some more study just in case. I know where you can get more in the USA but I know that is a hassle for you to order out of country.
I almost ordered some but in the end I went with species I thought would be easier to breed but the prices were good. I think they were only $7.00 each.
