These are autosexing Olive Eggers, a hybrid of a Welbar cockerel and a Cream Legbar pullet.
We have been making this cross for a number of years and the pullet chicks have been very popular. Hybrid vigor is always good and these have that, as well as the dark green eggs.
Like Welbars, these come in 2 colors, gold and silver. They look very much like Welbars, but usually have a small crest from their Legbar mother.
