Well, I have to say my first thought was to tell your husband your rooster's sterile and the eggs aren't fertile, he'll never know the difference............I'm so bad
Sorry.
I think your idea is great. Plus, you could change what hens are with him if you need to, say someone gets to be too much of a "favorite" and looks ragged. You have 9 hens, so I wouldn't keep more than 2 separated from him at a time, leaving 7 for him to spread the love. I think those 2 hens would be fine not being with the rest of the flock.
I agree, carry a sharpie and put your honey's initials or "Dad" or whatever on it. Or, if you have hens that lay different colored eggs, you could separate that way. Looking at your sig line, you have two green egg layers? Those could be your honey's eggs, easy peasy, no marking!
