Good for you :)
Id imagine these birds lay down to eat often and are missing feathers from there tummy and breast area? Do they act like they are starving anytime you put food out there?
If you aren't already, you can try to transition to something that is really low in protein. I am not...
We used to raise them for broilers, but decided to take a different approach. They are super fast growing and have a great feed conversion bjt there was something about how unnaturally fast they grew that began to gross me out.
Oh boy. Those are broilers.
They will become very unhealthy the older they get, and likely won't live past 1.5 years. They are intended to be butchered no later than 12 weeks.
