It is quite common for tail feather follicles to be damaged if they are picked out while they are young. Even if they don't grow tails now, after the first adult molt the tail will probably come in, but may not have the shape that nature intended. That black one appears to have a cushion or rose comb - are you sure it isn't crossed with something else? It is hard to tell from that photo if it is male or female, because the lack of lighting obscures the saddle and hackle feathers. You can easily tell if a bird has a missing tail or is just missing feathers by feeling that area to see if there is what is commonly called "the parson's nose," which is properly known as the uropygium.
