People who keep chickens do some really weird stuff.
A few examples;
They put little jackets on their hens that cover the hens back in an attempt to stop the hens feathers getting pulled out during mating.
They cut the roosters spurs! How weird is that? The rooster is supposed to have spurs. Sure, if they are so sharp they damage the hen, filing the point smooth makes sense.
They cut off the roosters comb because some people think this looks better or because the combs may get frostbite.
Some people put baby nappies on chickens that they keep in the house.
I’ve read of people putting golf balls in nests to encourage hens to lay their eggs there.
I let the chickens wander about in my house.
