What breed is my rooster?

[Dalia]

I’m trying to figure out what breed my rooster might be. He is large, orange, very fluffy, and has a lot of feathering on his legs. He hatched from a light green egg.
I currently have White Leghorn hens, and I’m wondering what kind of chicks I would get if I crossed him with them. Has anyone ever had a similar combination?
What egg color could I expect from the daughters?
And what would the chicks likely look like (feathered legs, size, color, etc.)?
I would really appreciate any guesses or experiences. Thank you!

I think probably Brahma mixed with Easter egger, since he came from a green egg.

Brahmas lay brown eggs, and it's uncertain whether he carries the gene for colored shells or not. So the hens from him could lay light brown tinted eggs, white eggs, with possibly some laying green eggs.

The chicks would likely have feathered legs, but it's not a certainty. Since most white Leghorns carry the gene for dominant white, chances are the offspring will be white with some red/buff leakage but no black. The offspring would not be as large as the rooster, since Leghorns are a light breed, but they would be bigger than their mothers.

Hope this helps.
