Has anyone tried rearing the boys (castrated of course) and training them to pull carts? a good excuse for keeping those little favourites? 
Well ... when our we had our first kid, we kept him (castrate) for about 9 months. I tried to train him, but he was an awkward little chap, and his mum freaked out when he went out on his lead, calling him etc.
She absolutely will not wear a collar & lead, although her foster-mum was lead into the house every day for milking & for walks round the garden etc... she just waited quietly til she returned!
As for kids - we've had the following experience:
foster-mum arrived with day-old Geraldine who had some bottled & some "direct" milk once they'd settled. She self-weaned, and we milked Margo a little bit twice a day.
Geraldine's first kid (Max) was self-weaned, Margo had died so we knew we would have to keep him until there was another companion for Gera. We milked her twice a day ... and she hates it! She prefers a once-a-day evening milking, with a bucket of food & veggie treats. (Aren't they funny!)
Her second kidding was twins, we left them & just "eased" a once-a-day milking until they were about 8-10 weeks ... then we rehomed one & Max the first-born. We then got loads of milk, and the other self weaned.
This time round, triplets! the two boys were rehomed very early, and are bottled.
We are getting about 1.5 to 2 litres of milk a day ourselves & she is feeding Heidi the little girl.
There have been a couple of days when we left it all for Heidi, she is growing into a giant!!
It will depend for you Plums on whether you get hims or hers...
and how Puffin reacts. Do you have her in a "milk" routine? and is she comfortable with you touching her "quarters" (or nipples, as they are called here!) just so you're both really prepared!
I have to say, personally & imho, I don't feel comfortable separating kids from mums unless they leave the premises altogether. And I make no decisions until I know what we've got (i.e we said with this kidding, the boys would go asap, but a girl or two could stay longer! And I don't like them going off on their own either! But until they arrived, we didn't know even how many were coming)
hope that made sense ... I'm abit too tired for coherent typing
