my mum's chooks have been pecking on the water container and they spill the water everywhere. Why do they do this.
there's nothing on the outside of the container that i can see.
breed: isa browns
name: tess at the back, vera and wanda at the front
gender: females
age: vera and wanda are 2 years old and tess is 4-5 years old
our girls are very smart at getting treats by pecking on the back door
