Most of my girls have spurs. They lay blue eggs that hatch into auto-sexing chicks. Those are the 2 key points I worry about.

Is it normal for Legbar hens to have big spurs?
Both of mine have them
Thank you Thank you! This is the best explanation that I have read about autosexing breeding.Legbars and Welbars are both autosexing, meaning they have wild-type chick down plus sexlinked barring (there are a few other genes they should NOT have to be properly autosexing, and they lack those). Because the genetics of autosexing are so specific, crossing 2 autosexing breeds will always yield autosexing chicks. I created Welbars from my Welsummers (see welbars.com for the story) and they are very strongly autosexing and produce eggs as dark as the Welsummers I created them from. By crossing them to Legbars, I get autosexing Olive Eggers. These will breed true for autosexing, but not necessarily for egg color, meaning if you cross a pair of these OE's, about 25% will lack the blue egg gene and lay brown eggs. Because of the unpredictability in the F2, I do not plan to create a true breeding line of autosexing OE's, but rather continue to use Legbar pullets in my Welbar pens to create as many OE's as I want. They also pick up significant hybrid vigor and seem to grow faster than the pure Legbars, as least from what I've seen so far. The cross would work equally well the other way (Welbar pullets) but I have more Legbars and they lay better and hatch better than the Welbar eggs. Last batch of 29 OE eggs resulted in 29 chicks, and 22 were pullets !!
"Sexlinks" are altogether different thing. There are 2 major coloring variations in sexlinks, Red and Black. What you saw in your chicks was the Red sexlink effect, even though the birds were primarily black (right? I've never done that cross). Because both parents are fully barred, there is no way to create a Black Sexlink from this cross. You can easily create Olive Egger black Sexlinks with either Cuckoo Marans or Legbar pullets, covered by the opposite egg color black cock, like this:
1. Cuckoo Marans pullets X Black Ameraucana roo
2. Legbar pullets X Black Marans roo (Copper or plain black)
In both these crosses, the male chicks will have a white head spot and barred feathers, while the female chicks will lack a headspot and feathers will be all black. If there are any I am not sure of, I wait a few days and check the tips of the developing primaries, any white tipping indicates a male.
