I would like to give some feedback about ...

This is not good question. Look at this:

If you have 5 portion of food:

• 1 minute: 5 ( portion ) - 1 pigeon | 1 pigeon eat full portion
• 2 minute: 4 ( portion ) - 2 pigeons | 2 pigeons eat full portion
• 3 minute: 2 ( portion ) - 3 pigeons | FALSE 3 pigeons > 2 portions

For 5 portions of food only 2 pigeons will eat full portions
