Chicken Gizzards

So, I'm cooking some chicken gizzards (hearts, kidneys, etc) to give to my dog/ferret. I'm gonna boil it, as my ferret won't eat cooked meat let alone raw (I'm gonna start getting him on it)

Question is, how long does it need to/should it be boiled for?

I guess you found out by now that it doesn't take long to cook them through

No idea, just boiled them til I got sick of waiting, didn't care if they were cooked or not lol
