Suggestions for tempering:

• Reduce number of eggs given
• Have a time interval between feedings
• Worms decrease the next egg lay cycle of the chicken rather than give extra eggs.

At the moment I am inclined to do the last one.

New behavior:

• If the chicken is a child, it will be made into an adult.
• If the chicken is an adult, the egg laying timer will be decreased by a random amount. Keep smacking the chicken with worms to get eggs.
• Only one egg will be laid.

Fixed.
