Yes you are correct, he does appear to have a squirrel tail which would be a disqualification if that variety was in the SOP. One of the females is also holding her tail high. I don't know how old the male is, but they should also have a nice wide bowl-shaped breast. His breast is very shallow. I can't comment on the color of the birds since I don't keep that variety. Just some thoughts, since you are a beginner to show birds, get a breed that is in the SOP so you can show and compete. Get a breed/variety that does not have a complicated color pattern that is much easier to breed correctly. The late and much loved Bob Blosl, over on the Large Heritage Fowl thread, used to post all the time about how beginners wanted fancy colored birds that are hard to breed right. Then they would get frustrated after a few years and give up. Since you are talking show birds, I assume you want to breed them right.I'm sorry, I meant the, like, body type and comb and everything.
The only faults me and my friend could notice seemed to be that the tail looked like it was held a bit high and the head shape was off, but we are both beginners to the show bird world, so we are probably incorrect.
