As he is almost old enough to be neutered, ideally wait until both he and his brother are done. It’s best to then wait a month until any hormones in their systems have depleted then start introductions in a neutral area. i.e a space neither rabbit has spent time in.

With the group, ensure now that the males and female are separated if they’re becoming sexually mature. Your parents might be on top of this but a reminder won’t hurt. ;o)

Normal logic seems to go out the window when rabbits are involved… lol.

A few things to clarify:
1) It does not matter that they are siblings. When they are reintroduced, they will regard each other as strangers. So if unneutered, they most likely will fight.
2) It does not matter if one is currently in a group and one is not. Every rabbit relationship is unique. Some pairings work, some do not. Just because brother is with a group does not mean he will be easier to bond. And just because your bunny is single does not mean he will be more difficult to bond.
3) Size certainly does not matter. There are some very gentle giants and some downright nasty dwarfs. Just because your bunny is smaller, does not mean he is in danger simply because of his size, and this also does not mean that the larger bunny will be more dominant.

If the brother is already in a group, why are you looking to split them up? Is the sister separated from the remaining boys? If so, and she’s by herself, I might consider taking her and introducing them after they are both altered. Male-female bonds tend to be easier, but it is (of course!) imperative that all buns are spay/neutered.

Very sweet. : ) I just love the name Little Grey too by the way.
When you have them both at home but separate, be sure the is space between their cages. Rabbits can even breed through cages!   It also will prevent any nose nipping.
 

Once the time period after his neuter has passed hopefully you’ll have a smooth introduction between them. Here is this site of basics of bonding: https://www.binkybunny.com/BUNNYINFO/BondingInfo/tabid/63/Default.aspx

Also another article on bonding that is really good in my opinion.:http://www.rabbitnetwork.org/articles/bond.shtml

Hope that helps.

I believe rabbits can smell right through the onion and garlic but it may serve as an olefactory distraction… I would not use any plant from the garlic/onion family though because they will groom it off, and these are powerful plant juices that are not safe for rabbits to ingest. Maybe rub carrot juice over them instead. It won’t be as potent but it will be pleasant to them~

I’ve heard of it before but honestly, who wants a garlic-onion smelling bunny?
Though I am interested to know what book this was in?

To me, an intact male kinda smells like onion-garlic… you know, the scented droppings

I know exactly thanks to Jersey (spayed female not intact male!!)

when was that book written? the year?

i read rabbits for dummies. good book on information.

Britt: Thats one of my favorite books to.

the book is rabbits, a complete pat owner’s manual. bought at pets unlimited. i have a new problem on my hands. carrie my new bunny is actuly 7 months and was living with her brother untill 2 weeks ago so will see what happens if she has babbies.

Oh yikes! I suppose if she was going to have them she would have during the time she was there. But if she was impregnated right before she left, you’ll know within the next 2 weeks.  Are you prepared if that’s the case?
 

Do you plan eventually to get Carrie spayed?  They can actually do emergency spays but I’m not certain if it would be too late for that.  Some don’t like this option.  I’m not even sure I would be comfortable with it but just letting you know it is an option with an experienced vet.

I would also encourage seeking a vet’s opinion on an emergency spay.
