I
am sure we have all experienced spraddle-legged youngsters
in the nest. Here one or both legs splays outward
producing a deformity in the leg or legs. The deformity
is mainly in the ability to position the limb in a
proper posture; but can also result in true deformed
bones or joints of the involved leg(s).
The
condition results from insufficient traction in the
nest bowl. It happens most commonly when there is
a single nestling. The second nestling usually provides
something to push against for the other nestling,
and the side of the nest bowl provides the same thing
for the opposite leg.
The
nesting material is the other factor in providing
adequate traction to the growing squabs. The parents
usually cover the squabs providing extra weight for
them to bear, and if adequate traction is not present,
the leg or legs tend to push away from the body producing
this condition.
The
involved leg can end up pointing 90 degrees or more
away from what would be normal. I have even seen them
where the rotation was so severe that they appeared
to be pointing backwards. Of course the longer before
they are noticed, and the worse the deviation, the
harder it can be to correct the problem.
This
can usually be corrected by the fancier. First, adequate
nesting material to provide decent traction needs
to be supplied. The legs then need to be "hobbled",
or bound together to approximate a near normal or
slightly overcorrected posture.
One
must be careful not to attach the binding material
too tightly around the legs so as not to disturb circulation.
A relatively soft material is better, so as not to
cut into the leg tissue since there may be quite a
bit of tension on the legs/material. I have used soft
twine or tape to do this job, often using the band
as a starting point, attaching to the band rather
than the leg to distribute the pressure more evenly.
Next
bind the other leg to pull them together without constricting
the leg. It usually only takes several days to a week
or so to accomplish the correction since the squabs
are growing so fast at this time. Remove the binding
when it seems to be time and see how the squabs leg
posture appears.
One
can always reapply it if it is not corrected adequately.
Some may not be completely correctable depending on
severity and timing on the corrective process. The
success rate is high and certainly deserves trying.
