Can feminized seeds be used for breeding?

Like the freebie seeds from attitude NL and DP. I have some ideas on a few crosses i'd like to try with these but would like to now if it can even be done.

i have never heard anything good come out of breeding fems.
unless maybe using them to make more fems of the same strain.
but just because ive never heard anything good doesnt mean it cant be done.
id love to hear some other opinions. maybe from someone who has tried and they can share their results.

if u would like to follow along i had some feminized dp blueberry crossed with a female nirvana bubblegum that hermed on me and seeing that i couldn't find any info on seeds like this i'm trying 5 of them to see if they are hermie or not..*GUESS for DOUGH SHOW*

So far its sounds like a no go but i'd still like some more info.
