No. Once a chicken lays a certain color, they will always lay that color. The egg shown is a shell less egg. It happens occasionally with new layers. The blue is put the shell just before laying.
That has not been my experience with them. They were accused of abusing the chickens a few years ago and it turned out it want them However, the rumor sticks. I got beautiful birds from them. All hens and exactly the breeds i wanted.
Only ever clip one side. Same side every time. On every chicken. This makes them fly crooked so they can’t get as high and over what they are aiming for.
Do not clip until their adult feathers are in. While they are growing, they have blood on them. This would be the equivalent to clipping your dogs nails too short and cutting the quik.
