You might find some tips in the web article “Boys to Men” — http://musiced.nafme.org/interest-areas/choral-education/boys-to-men/
One of the suggestions: Arrange for a male volunteer or two to come and sing with your boys for a couple of rehearsals. Especially if you (the teacher) are female, it will help them greatly to hear someone singing in their own octave. Ideas: other male teachers, college students needing community service hours, retired men from a local church or community chorus, or barbershop chorus.
