"Zazzle" would be a just fine rooster to use with this program. What I'd suggest is keep the barred in only one parent - so you don't end up with homozygous barred anything that will only produce 100% barred chicks. Not that barred is bad mind you - it's just you end up committed to only one color that way. LOL. Personally, I like having a lot of colors in my flock! Which you can pull off if you use the right boy.
In my case, I used the barred rooster over non-barred hens, and the barred hens wiht a non-barred rooster.
If you don't have two pens, to keep them apart, use "Zazzle" to improve one generation, and keep his daughters.
But I like his overall look, and his legs look pretty solid too - not sure how much weight he carries? He looks like he might be a little "meaty" or dual purpose?
