I'm so sorry. How did the snakes get them?
I haven't figured it out.
My brooder is currently dirt-floored and was sitting on a packed gravel pad left in an inconvenient place by the previous owner. Gravel so hard-packed that we can barely get through it with a pickaxe so we considered it safe vs digging predators.
I'd *thought* I'd found the hole under the bottom that the first snake used and blocked it up, but two more chicks vanished a couple weeks later.
I'm going to put a floor in it and add a door jamb -- just in case the door had warped just enough for that to be the problem.
