Tilly and Duncan, for those that are not familiar with them, are our current bonded pair.  They are very affectionate towards each other but still pretty independent buns in their free time.  When Duncan gets insecure about Tilly giving attention to humans more than to him, he will nip her bum until she turns around and snuggles him instead; but otherwise they don’t have any real squabbles anymore.  They are free-roam in our townhouse during the day, and return to their room when it’s bedtime or when we leave home.

We’re going to be hosting 2 fosters, a brother sister pair, that will have a pen set up downstairs.  They lost their bond when hormones kicked in but we’re looking at re-bonding them as it would do well for their personalities and also in housing situations.  It will be about 4 weeks since their appointments once they get here, and there have been no signs of hormonal activity for a while now.

I figure the fact that they will be in a neutral space in my home it should help, but I’m concerned about how Tilly and Duncan may factor in.  We don’t have a separate room to set them up in, as the only closable room is already Tilly and Duncan’s home-base.  Tilly and Duncan like to spend most of their time upstairs, which is another reason for the fosters to be downstairs. 

My question is for those that have had multiple pairs or multi-bonds in their home:
Do you think Tilly and Duncan being present may hinder bonding my foster siblings?
My free-roam space probably smells like bunnies since mine chin everything… do you think that will upset the new fosters?
Do you think the fosters being here (even contained) will put a strain on my current pair? Duncan is insecure and moody, but Tilly is generally friendly and just licks new people/critters.

I’m sure this can be done or I wouldn’t be bringing them in; but any input from someone more experienced would be appreciated.
