I wouldn't trim a beak unless I noticed it was causing the bird a problem with eating. If you're giving scratch, are you also offering grit? The other thing to think about with a bird housed indoors is Vitamin D supplementation. Although, if you've only had them indoors a short time, it isn't likely they would have developed a deficiency so soon.
Your hen may not be laying because of lack of light, though.
