My Jake, Bourbon Red, was a GREAT father. Loved his kids, slept with them, guarded them, let them ride on his back, even tried to mother them when the fox got the hen. While new fathers - just like first time broodies, make mistakes. It IS a learning process and if they're so inclined, they're invaluable.
I'm sure he'll look after his next brood even better and the whole flock is better for the experience because THEY all got used to having babies under foot. So the subsequent batch of chicks to two first time chicken moms actually went very smoothly. While there are losses with both broodies and fathers, especially the first time. Who among us does everything right the first time? I let him learn. They lost three, kept three. But the entire flock is better for it.
I'd rather lose a few and ensure a better flock dynamic, but that's me and my free ranging situation talking.
