Extremely slow feathering Rhode Island red pullet

[SJsChickies]

Im seriously starting to think she is a super slow developing Cockerel. Her hackle feathers look very pointy and her tail is super shiny, 2 feathers longer than others and pointy ish. What do you think? I would say definite Cockerel if it wasn't for the pale tiny comb and no crowing.
