Or, hell, just bludgeon a rat and roast it over an open fire.
Chicken water... hmmm... well, if you took a chicken, and put it in a hydraulic press, then I imagine you could call the result "Chicken water".
Hey- does that mean that, if you included all the other desiccated stuff that'd be left, but in powder form, you'd have Instant Chicken? Think of the possibilities- you'd just add the chicken water, microwave for two minutes, and you'd have a live chicken again, ready to lay eggs! And when you needed to store it again, you'd just take out your portable hydraulic press, check that no SPCA members were in the area, and repeat!
Or you'd get something really disgusting. Either way.
