Hi! Welcome to BYC. Remember whenever you have any questions about your chickens or when it doubt turn to BYC! It’s a great reliable website with professionals and people who are learning every day like me! Hope you enjoy BYC!
Welcome to BYC. I'm glad the website has been useful to you so far, and I hope it continues to be so. Boschvelders look like a cool breed. I'd never heard of them before. As far as the broody silkie goes, 5 months is very early for that. If she is healthy and vigorous, and is close to adult size, I think it will be okay. If not, maybe you could slip her eggs under another hen and try to break her of her broodiness.
This is a useful link of BYC guides to take a look at announcements-feedback-issues-guides.3 I’d suggest including your location using the guide in that link.
As you already know, chicken watching is a wonderfully entertaining hobby. I just suggested yesterday that we get rid of our DISH subscription and just sit on the deck and let the poultry amuse us (Okay, I was kidding because winter in Iowa is not amusing no matter who or what is in your yard).
Clearly, people here are willing and able to offer great advice. Welcome to BYC and good luck with your chicken keeping, whether you decide to hatch or not.
