Looks better already! Same as trimming a dog's toenails that have grown much too long, it's not possible to cut bird beaks back to the proper length the first time without cutting into the quick. With the end of HER(!) upper beak being light in color, that should help guide you to not cut too close. You could even draw a line with a marker below the quick before her next trim. Looking at the second pictures you posted, her lower beak looks to be chipped off at the end, which is likely what enabled the upper beak to grow too long.How did I do?
Also looking at the second set of pictures, there is NO way her comb is that of a 14 week old EE cockerel, even though as you said, she is unusual looking. How does her size compare to your other pullets? Please update this thread with more photos of her growth in a few weeks!
