Will it ever end???

Well, another sad morning.  I noticed this morning that my 2 white silkie hens were missing from the yard.  There were no signs of anything, no feathers, no blood, no trail of any kind.  Of course, silkies are pretty small and would be easily carried off with no signs left behind.  We've had the silkies for 4 years now...this was their home and I failed to keep them safe.  I can't help but take responsibility.   We have to get better housing figured out to keep from losing more.
