Splash is a plumage pattern. There is a description of it in the Bantam Standard. Splash is generally made as a result of breeding BBS birds. All Splash birds regardless of breed are measured against that plumage pattern description. Splash is not yet an accepted variety in Cochins but there is a group working to make that happen. All Splash can be shown and will be judged using the description of the breed and the plumage pattern description as the benchmarks they are judged by. Until acceptance as a variety the best a Splash can get in a show is BV- Best of Variety not accepted so can not compete for BB- Best of Breed or higher. Some shows will pick AOV - any other variety winner but again can not compete farther than that.
