Welcome to BYC! I think I may have to agree with Chookwagn...incubating your own eggs to hatch & raise may just be the best option. The good news about that is you get to do this on your own timeline - and you probably couldn't have picked a better place to learn everything there is to know about the process from beginning to end! In the meantime, you could try building more trust with the current 'feral flock' as you learn more & who knows, maybe one of the young ones will form their own home base on your side of the fence
