Ryan:

This may not even be a "electronic" problem in the sense you are looking
for a average weight, and any individual variances among a specific bird
would mean little.

Your really need to break this down into equation, and attempt to
minimize the number of "unmeasurable" variables

You have inputs into the system, and outputs from the systems.

Inputs:

Water
Food (feed)
The growing chicken
Time
Temperature

Outputs:
Chicken waste (Feces&Urine)
Chicken mass (meat)

Factors needed:
Typically Chicken efficiency per breed in converting food to mass


You easily can measure water input, Food consumed, temperature and time. Each
breed of chicken will will have a typical conversion rate of feed/water into waste
and well as mass.

So I think this is less of a electronics problem, then simply looking at a populations
intake and developing formulas to calculate average weight.

That much being said, I'm suprised such a formula doesn't already exist in this
field. Might want to look around.

Good luck
