looks like baby feathers to me that will shed out. just looks like immature bird...Ive seen a true split wing there is no feather there and a gap..that just looks like shedding baby feather and adult feather coming in. an angel feather twists that just looks like its about to be replaced..my freind had a del rooster that shed his babys like that ..once his adults were all in he was one nice boy..the judges know trust me..they expect that in juvinals...most people time showing thier birds between 5 and 8 months for cockeral /pullet..they seem to bloom during that time. they never have that young bird bloom again..
and PS..
I went to several APA shows last year..shes probably the nicest one Ive seen..there was one outstanding female del at one show we went to we just stopp but most were not that nice..and so few of them , very few..there were walls full of of barnvelders and d uccles and only 2 delawares..pretty sad for this wonderful american breed..would like to see more of them at the shows..there were a few at the fair ..the judge wrote TC on the tag meaning something with the tail color..there were some killer dels at the PA farm show but just ttry and get ahold of the breeder..Ive snail maled him, Emailed him and cant get ahold of him .. somebody told me that back during the 40s and 50s you would see 30-40 dels at a show, now your lucky to see one or 2.
