Feeding Indian Runners
One of the first things new duck keepers want to know is: 'What
do ducks eat?' There isn’t a simple answer: the diet varies
depending on the time of year and the conditions under which your
birds are kept. If ducks are genuinely free-range they will find
most of their own food. This will include a lot of slugs and worms
and insects found in the grass, stream and garden. Their diet will
also include greens, such as grass and duck-weed. Birds fed like
this will have tight, glossy feathers and a bright orange beak (in
the orange/yellow billed breeds). This bright colour comes from
natural substances found in greens. However, most of us cannot allow
our birds such liberty for fear of foxes. Also, even free-range
birds do not mind being offered food from bags, especially to fill
up before a long winter night.
Winter food
The best all-round food is wheat. This is why it is used as a basic
food at such places as Slimbridge (Wildfowl and Wetlands Trust)where
it is fed in the water, at the water's edge. Wheat contains more
protein than maize, and is higher in vitamin B. It is also cheaper.
There is no point in buying ‘mixed corn’ which is basically wheat
grains and split maize. The cut maize is the yellow bits. The only
real benefit of maize is in very cold weather when it provides extra
calories and oil which may help to keep the feathers supple and
waterproof in winter.
On rainy days, when pellets left out in the open are spoiled, ducks
can be fed wheat under water. If the bucket is well filled with
water over a small amount of wheat, this also makes the Runners wash
their eyes.
Laying ducks
If your Runner ducks are laying, they do need layers pellets (with
additional calcium and phosphorus). Feed these pellets dry in a bowl
at the end of the day, or make a permanent canopy for the food bowl
to keep the rain off. Poultry layers pellets will be adequate, but
hen layers contain additives such as egg-yolk colour, and the
calcium content is too high for the drakes. That's why it's a good
idea to offer wheat as well. The ducks, which need the pellets, will
eat more of those; the drakes will choose more wheat. If you want to
keep things simple, mix layers pellets and wheat 50:50 dry in a
bowl.
Care of breeding birds
When birds are due to lay, the duck looks fuller in the abdomen. A
duck-breeder pellet ration should be offered from the beginning of
February. This is more expensive but it will contain more vitamin A,
D and E than 'maintenance' and 'layers' rations. The trace element
content also differs. If you want ducks to breed, they must have the
correct diet for healthy embryos. It pays to give them the best
food—and this includes free-range food if they can get it safely.
Calcium and phosphorus
Egg shells need calcium and phosphorus for their formation. That it
is why it is important to feed a quality breeder ration in the
spring where these two minerals are available in the correct ratio.
They are also available in the correct ratio for eggshell formation
in hen layers pellets. Anderson Brown (The Incubation Book) cites
the correct ratio in most breeder rations as 3% calcium to 0.6%
available phosphorus. Commercial layers' pellets can be as high as
4% calcium.
You could help the ducks get enough calcium by liming the ground if
the soil is acidic. This may be needed in high rainfall areas in the
west of the UK. Calcified sea-weed is probably best because it
contains trace elements too.
You should also make mixed poultry grit available. This can be
bought loose from pet shops, or in bags for about £5.00 from poultry
feed stockists. The birds love to select the grade of chipping they
require from underwater. If you have a small stream, just leave the
poultry grit loose in the water, or contain it in a heavy,
broad-based clay plant pot in the water itself. This will keep the
chippings clean. There is no need to worry about the ducks getting
too much calcium from the environment. If the ducks do not need the
extra calcium, they will not pick up the lime-rich grit.
Insufficient calcium and phosphorus may also be a contributory
factor in the ducks' having difficulty in passing eggs and becoming
egg-bound. This can also contribute to prolapse. So, do make sure
that your birds have breeder rations in the spring. If you cannot
get these, then ordinary hen layers' will have the correct ratio of
calcium and phosphorus—but not the correct vitamins and trace
elements for breeding healthy ducklings.
