Oh my! I can see how you would get nervous when it is dark out.
Have you thought about a lighted run that can be made secure. I had to use one once for a while until my fence was built. It worked well and I was able to see to it that it was really secure. Put lights up on it for when I got home to late and it was dark.
Best of luck to you. Keep your other babies safe!
