Your cockerel has silver leakage in all of the key male areas- hackles, shoulder, and saddle that would not fare well in a show. If you are looking for show potential in hatchlings, you should look for a replacement male in your breeding program. Does your pullet/hen have the proper pea comb? It looks like a single comb in the picture but it can be hard to tell without a close-up. It might just be the lighting. The blue color is currently under serious work by a few different breeders in hopes of developing the crisp, dark (black) lacing that one sees in Andalusians. The ideal blue would have that clearly defined band of black around the blue feathers, but most Ameraucanas have more edging than true lacing. If you do choose to breed and hatch from the birds you have, it's best you think of them as Easter Eggers and just enjoy them despite their faults. Just because they don't fit the strict standard doesn't mean you can't have fun with them! I had a Blue Ameraucana that unfortunately had some stubs on one shank (who knows why) and she made a great broody hen and was a decent layer.
Luckily for you, blue is based on black (one dose of dilution makes blue, two makes splash) and the blacks are the best developed and most frequently raised of the breed. You could pick up a really good quality pair or trio of blacks and test mate your female to the black cock of the trio to see whether she possesses leakage as well. Her male offspring would be the likely tell-tales. If you want to raise them for a show whether it's for you or kids in 4-H, there are lots of helpful mentors to be found in the breed club and the thread shared above.
