Have anyone has sucess breed their own meat bird from Red Broiler or Freedoom Ranger?

I purchased a pair of Red Broiler on March 23. They will be 5 months next week. The fullet doing very well and she little larger than Bielefelder hen. The cockerel is clumsy and almost die 3 weeks ago. He couldn't move and lay most of the time. I treat them just like my other layer so no special feed. The 2 dark cornish in the photo are 12 days older than the broiler. They live together since March.
If anyone breed Re Boiler or Freedom Ranger before, I would be curious to see how their offspring turn out.
