As I said earlier the autosomal lacing is what you would expect and is absolutely normal. Patterns such as Partridge as in Wyandottes,Plymouth Rock only have the Parrern gene Pg, Double laced as in Barnevelders, Dark Cornish have the same Pg + a melaniser Ml, single laced such as Wyandottes,Sebrights have PG + Ml plus Columbian, autosomal pencilled as in Hamburgs,Campine have Pg and Dark Brown Db, spangled as in Hamburgs have Pg Ml and Db.
They all look the same in the juvenile feathering stage.
