I heard that when a bird is sick in the flock, that it is pecked by the other members. My rooster pecks one of my hens a lot. Is this normal, or should I be worried. Please I need help.
If any bird gets wounded, though, the others may start pecking/picking at it making it worse. You'll sometimes have to separate birds if this happens. Other than that, your rooster is just showing them who's boss.
Also, when roosters first learn to mate, they're pretty crap at it. I find until they get their rhytym, they'll be pulling and tearing at the hen's heads moreso than they will later on when they find their mojo.
