Up until this week, I have left the light on at night to encourage them to eat frequently. The helps them grow really fast. This week, I have begun to turn the light off at night, to let them sleep and to slow down weight gain in this final week. They have reached the weight needed for processing...the deed will be done shortly after sun-up this Sat, unless one of them develops complications like leg problems.
Them's some BIG BIRDS!
