Putting more weight on the males

[Nieve5552]

I've got a cage of 5 males I'm wanting to process soon. They're feeling pretty small and slim at 6.5wks old, they're doing a lot of jumping /running around from each other with their mating instincts. Haven't got injuries or bald head though. Any idea how I can fatten them up for processing?

Gamebird feed available at all times, a few hides also available in the cage for them to use. Dust bath occasionally available too (all the sand gets kicked out and I refill maybe once a week).

I’ve been using this and it’s put the weight on my birds fast. 28% protein.

Any way you could keep your butcher birds to 8-10 hours of daily light? It would prevent sexual maturity and direct energy towards growth. The 30% protein feed really does push the growth, I cut back to 21% for my flock as meat isn’t my focus just a byproduct and the hens were laying 30% weird eggs at 5 weeks. Now I get 99% normal eggs at 7 weeks, slower but probably better long term for the layer flock.
