If you /your daughter want to keep both boys then I suggest you have 2 separate coops, that's what I have done with my 2 boys now and if you can get more hens for them both then great
I have 2 pullets with 1 cockerel and 3 pullets with a rooster. (Also a hen with 7 chicks in another coop).. That setup works for me and my chickens anyway. Chickens behaviour varies so what works for me may not work for you.
