Yellow pear are totally delicious.
the only simple solution to no snakes in this area is to up and move the the south of France :-)
They are simply everywhere, having a garden with chickens does not help one bit. :-)
nothing really keeps them out. things you can do... but its always a possibility.
we live in suburbia, so no real birds of prey, we do have pretty big crows and kookaburras, but they can't take on a grown snake. They will nab a baby every now and then though. These guys kill cats and dogs. Dogs being pretty susceptible to a bite from these guys.
Here is Australia, most stuff tries to kill you. lol.
Glad the tomatoes are tasty, nothing like home grown fresh of the vine. My kids are always in shock when i tell them how OLD the veges are they ate from the shops. who wants to eat a 2 year old apple. yuck lol
happy gardening
