Can someone explain the "blue" genetics to me?

[RuffIedFeathers]

I've read a lot of different things and I'm not sure which is correct?
Let's use blue Australorps for example.
So if I breed a blue hen to a blue rooster, do I get all blue hens? What about a black hen to a blue rooster? I'm just really confused. I see info that says you can get black, blue, and splash? Can someone point me towards something to read to get the correct information?
The blue and lavender colors is chickens interests me the most, so I would really like to learn. Thanks!!

This should get you started without feeling like you’re drinking from a firehose.

First: Blue is a completely different gene than Lavender/SelfBlue. A bird can have one of those colors, both or none.

Blue is a dilute of black. A bird with no blue gene is black, a bird with one is blue and a bird with two is splash.

BluexBlue makes blue, splash and black.

Blue to black or splash will make blue and whatever the other color is.

BlackxSplash will make 100% blue

So if I had both blue and black Australorps hens and could only have 1 roo, would it be better to get a blue or a black roo? Yes, I want to breed high quality birds, but this is also for experimenting/fun. Thank you!

Blue if you want a chance to produce all the colors.

The way you said this is confusing. A bird can express both the lavender and blue genes, in fact I had a hen like that for the longest time, it’s just not to be found in pure breeding flocks, or to be encouraged.
