I like you automaticly assume lizards there. Here it's snakes. Snakes in the mulch bag, snakes in the potting mix, snakes in the sand and if you leave the lid off snakes in the sugar jarMy son and me were moving some sand and came across these... probably lizard eggs. From what I read we shouldn't have moved them - but then they already moved when the shovel reached them, we didn't know they were in the sand pile. There should be an old terrarium in the house with IR lighting. We'll see.
