Salt doesn't make or break the deal when you're soaking a chicken.@Eggcessive @Wyorp Rock @azygous
I'm not sure about the sensated salts, but I've heard you can use normal slaty water if your unsure. I may use them anyway as long as its a natural scent.
The warmth of the water is good enough on its own if you don't have Epsom salt.
I do not think it is safe to put this bird back in water but I am unsure so I would wait before doing so until someone who is definitely sure says to do so.... I am sure that doing so can be deadly.
