NEVER GIVE UP!

Yes, Id seperate them ASAP and look into tracael treatment not Varroa, just
a guess, but youd SEE the varroa.  Go watch them for a while, look at the
ailing ones, do they have K wing?

I choose to not treat mine if at all possible. Chemical treatment is of
questionable use as it is.  There is a large school of thought that says to
never treat with chemicals. You have some homework to do, and decisions to
make.  Gather all the facts you can then go look online and ask local
beekeepers what they think. Gather all advice possible and then make your
move.

Good luck and keep us posted!   Best get at it.
