Mrs Foster has been breeding Finn sheep for eight years and recently added two Damara sheep to her flock.
She said she was attracted to the Finn sheep by their short tails which did not require docking and the Finn ewes lambed at 300% or more.
''They have litters rather than single lambs, so we've had quintuplets and even sextuplets.''
The Finn sheep wool was ideal for spinning and crafts, while the Damara sheep had ''hair rather than fleece'' so did not need to be shorn, making them an ideal lifestyle sheep, Mrs Foster said.
As the Damara was originally from Africa the sheep were used to ''rough conditions'' and ate almost anything, including willows and rougher pastures.
''I like the old-fashioned or original kind of breeds which haven't had any interference from humans,'' Mrs Foster said.
She said her Finn sheep were starting to ''earn their keep'' as she was able to sell the rams to lifestylers and farmers wanting a ram for ''easy lambing''.
It would take another couple of years before the Zebu cattle paid their way, but the bull calves were finding their way to the freezer for now, she said.
A pair of Cape Barren geese, a breed originally from Australia, has been added to Mrs Foster's collection having been ''retired'' from Willowbank Wildlife Reserve.
Mrs Foster is helping to organise the Canterbury Rare Breeds Society's annual auction, at the Willowbank Wildlife Reserve on Sunday.
She said 230 birds and animals had been entered in the auction. While it comprised mostly poultry, pheasants, geese and pigeons, there would be plenty of rare sheep and some cattle up for sale.
