The other weird thing is that if he is opaline then all the males babies would be too. Right? Cause its sex linked? One of the blue ones looks opaline due to the blue grey on the back of him neck. My rp girl is opaline and has those same markings. I'm assuming male there based on the sex link. The other 3 must be females.
Also one of the yellow ones looks like its maybe spangle?
Let's see how bad I mangled it!
