I have a castrated male and spayed famail living together.
Happy and Ivan came as a bonded pair.
Happy unfortunatly died, so ended up with ivan as a house rabbit.
Got Lexi and let them run around my dinin room together as soon as I bought lexi home. left them for a few hours, under supervision. then put the together in the crate. and left them supervised for 4 hours before i went to bed. Came down next day and there was no problem at all. and hasnt been since over a year later :D :D
I got Lexi spayed as she was quite a feisty Doe and once spayed she calmed down no end!!!!
So my advice would be, get him castrated and introduce them.
BUT beware, females can live as a bonded entire pair for ages and then fall out with each other for no reason :(
So best get them all done!!!!
And best get does done before introducing as you have to keep them apart after op. and might unsettle them all to remove one for op.
Hope that all makes sense!!!
