Good Morning, Afternoon, Evening, Night!

Evening All .
Today I was chopping back the brambles behind GH No 3, between the GH and next door's house wall. Needless to say the dogs came to help. Ted was snuffling around behind the bushes, then I heard crunching noisestt and smelt something obnoxious. Was it a dead bird or rat or what? Ted wouldn't stop eating it, whatever it was.
Then Bess arrived and nosed her way in but instead of crunching, she carried something out in her mouth.
Hastily, I ran round to the kitchen door to make sure she couldn't take it into the house but she lay down outside and put her "trophy" on the mat. Then she ate it!! Fortunately, it didn't have the rotten smell of whatever Ted had eaten.

Any ideas what it might have been?

Eggs?
