Dominance issues?

Question
Hi Cassie, I have introduced a year old rescued unspayed female ferr to my home (Miss Foxy Brown).  Whilst Crow my 2 1/2 yr old male has bonded with and loves her, and she him, my 6 yr old female Blossom was indifferent to her at first but asserted herself on her arrival.  Bloss lost her cage mate Honey Pie May 21 but seemed fine.  Crow has a three storey cage as does Bloss, Foxy lives with Crow.  Bloss has always been a very independent ferr and was always the boss in the house, even over the cat!  Foxy and her got on well for 5 wks until Foxy cornered Bloss under the bath whilst playing and bit her on the flank.  Since then Bloss has been very wary of her and Foxy has been displaying more threatening behaviour towards her to which Bloss screams, even when Foxy isn't doing much.  I'm assuming Foxy senses Bloss's weakness and is vying to be top dog now that she has settled in to her new home?

I now feel unable to leave them alone to play, feeling I have to keep an eye on Bloss for her own safety and splitting them up when the trouble begins.  Foxy doesn't torment her all the time so she still has plenty quality of life, but I'm annoyed this has happened when all seemed well at first.  It took 9 months for Crow to settle in and I'm dreading the same scenario again - stress!  Do I have to let them battle it out, even with the age difference?  Seems so unfair.  I don't want to re-home Foxy as she and Crow get on so well, and being realistic, although Bloss is well at the moment, I realise she is an older ferr.  I don't want Crow to be left all alone.  Foxy is due to be spayed soon.  Will this help at all?  HELP!

Thank you Cassie.....

Answer
If foxy is unspayed she will likely not get along with any female ferret while her hormones are running high.

Once she is spayed I would try introducing her and Blossom slowly. And only separate if blood is drawn or you see poop or pee from either ferret while fighting. And only if you see one chasing the other constantly just being a flat out bully the entire session. I would start with short sessions first and always end on a positive note. And once they are sleeping outside the cage together or laying together try them in the same cage.

But I wouldn't try this until Foxy is spayed.
