Exploring an old barn around 11 am today (Mar. 24) at Freels Bend, Oak
Ridge, we discovered 5 intact white eggs (oval, about 3 inch long) on
the bare floor of a silo.  Numerous pellets and nuch white guano
splotching were found in another part of the silo, but no evidence of
nesting material or a parent in the vicinity.
    Eggs fit the description of a Barn Owl, and this species has been
found in this barn in previous years.  But they are supposed to brood
throughout the nesting period and should be roosting during the day
anyway.  Is it possible we scared the parent(s) away.  Are Barn Owls
likely to lay their eggs on the bare floor of a silo?
    At the other end of this very long old milking barn was a Black
Vulture, sitting beneath the floor, apparently either brooding or
injured.  Many similar pellets and white splotching at that end of the
barn as well.  But both vulture species are supposed to lay only 1-3
eggs, they are (Black Vulture eggs are not pure white, tho turkey may
be.)  Would vultures lay 5 white eggs on a bare floor in a silo?
    Looking for identification help,
