Blood loss might be vital and air sacs might need to be ruptured, so it’s a dangerous process, particularly with us not realizing the reason for Penguin’s difficulty absolutely previous to surgical procedure. The proprietor had religion and wished to do what was finest and relieve the discomfort. The proprietor has one other rooster, so we collected blood from that rooster as a blood donor in case we wanted blood in surgical procedure. We didn’t use it, however it was good to have a back-up plan in case we couldn’t management the bleeding.”
