Good for you. I love JGs. I've had black, white and blue but sadly don't have space or time for them now but would if I had more room. They're great birds.
I had some trouble with space myself. That´s why I sold my young royal palm turkeys and my cinnamon queens. Next year I am hoping that I can get some brown leghorns.
I've heard browns are nice. I like black leghorns too. I had one that went broody often and raised a bunch of chicks for me.
I grew up with huge flocks of white leghorns.
Once you get hooked on your black JGs, you may want to look into the other two colors.
