Pen one bird and the next falls right in line and so it goes. Every bird is an individual gotta watch em closely. I am trying to let each one be king for a few days at least before I pen them. It's going ok so far, a few minor setbacks here and there lol
For awhile the stags will run with a group of pullets and stay with them. As they all age though it changes. Gotta take it day by day and pay extremely close attention. I spend a lot of time watching from inside the house to see what they're doing when I'm not around. I've had just as many issues with pullets as stags.
All the other crosses were less than 5 months and the blues were all just about a week shy of 6 months. They don't give much warning though, one day they're good next day all h*ll breaks loose.
