Smebody sold you some very nice Sebrights.
Yes you absolutely should show them. At the last show I judged I made a Golden Sebright Pullet Reserve RCCL & your bird looks better.
They should be a good start. The only flaw I see is the male would be better if there was some Mulberry colour to his face & comb.
From my own experience with Sebrights I'd advise you to set every egg she lays. They aren't usually good layers & often have fertility problems.
Good luck with them.
