I have ordered meaties but am not sure about the chick part. I understand that they grow a lot faster and are ready for culling by 8 weeks or so. does that mean in the winter they can never go out? how long do they stay in a brooder??? Because they grow so much faster do they feather out faster as well??? My other birds went out in spring once they were 6 weeks or so. but by then I will be getting ready to cull them right???
