"IT helps to evaluate any fire warning with known (really known) cargo!"
I guess so, but does knowing that there are live chicks in the hold really alter your course of action when the fire bell goes? In what way?
A friend of mine had a situation in a wide body where they landed for a fire warning en route knowing that it was probably just the flowers in the hold triggering the alarm.
The local authorities would not let them park at the terminal (as previously mentioned by someone on this thread). So they calmly exited the aircraft via stairs only to find the cargo hold smoldering and damaged upon opening the cargo doors.
I know of two evacuations with injuries that turned out to have been simply live animals in the hold and in neither case was the crew criticized.
If the airline industry has concerns about unnecessary evacuations resulting from bird farts then they can come up with a viable solution to transport these items without triggering fire alarms. Until then, the only false fire alarm is the one viewed with hindsight.
