since ur's r 7mths old they would be listed as cockeral and pullet. no a person hired by them should be feeding all the birds however some shows do allow u to bring special feed to feed only ur birds, some do allow u to feed ur own birds. that is up to the superintendant in charge of show...
akright first thing u need to know is there is 4 classes under a year old is cockeral and pullet and over a year is hen and cock. sounds like ur's is the same way as the one i just filled out for NY, my last one we had to place them in dept and such also.
from what u wrote u'd need one line...
