Who knows if Moses in the cradle are/is dangerous to rabbits?
Valid question, but cray-cray is welcome.

Well, I was raised in the country by my grandmother and mother, with sister, on the grounds of my grandfather's asparagus farming operation, lots of shops barns equipment.
And we raised chickens, for sure, year round, nice digs for them, and what fun feeding them every day!
But one year a hen was killed by a fox or feral cat, leaving I think just one chick who we are allowed to tend to indoors.
I named her "PeePee", because of the sound she made. When PeePee reached chicken adolescence, you know that awkward age where their not so cute anymore but not adults yet either, we put her back out with the rest of the birds.
Some months later we were having chicken for dinner (we slaughtered our own) and, after the first few bites, it was announced that we were eating, yes, PeePee.
Obviously, it's stuck with me.
Which I believe means neither critter finds it tasty enough to eat.
Depending where you are, be careful where you put it - it can overpower native plants pretty easily. It's a huge problem in Florida and Australia. It's not cold-tolerant, so again, depending upon where you are, that problem might sort itself out.
Mine lives in my kitchen in California, so I'm pretty sure I'm not destroying native plants with it 
it was hard to resist a plant that purple.
