Ok, believe I have some good pictures for you to compare turkey eggs to chicken eggs. I have a gray slate and royal palm that lay and placed their eggs next to my brown and white laying chicken hens eggs for your educational value whatever it may hold. Lol.
So, the egg on the far left is a nice developed gray slate, spotted turkey egg. Top point with nice heavy bottom and not well spotted but faint tan spots but obviously larger than chicken egg which is the next egg to the right. Third egg to right is a pullet royal palm turkey egg. Small, almost chicken egg size, but yet has nice top point and obvious heavy bottom and tan spots but yet more the size of a chicken eggs. This was Nora's first egg therefore it will be smaller. The next egg to the right is another gray slate turkey egg but less spots. Still pointed and heavy bottom, larger egg. Sometimes their eggs will resemble more like a chicken egg but you can always tell by the shape....pointed top and pear shape bottom. Last egg, far right, is my Nella egg, which is my Polish chicken. Still a bit pointy but quite a bit smaller.
This shows you a different view of the eggs. If you look at them from the bottom, you can see the width difference and definitely the spots as well.
Hope this helps. I was truly tickled when my hens started laying so soon, 8 months old. Everyone told me it wouldn't be til Spring. AND, they both lay in the lil chicken boxes religiously unless they don't stay in coop over night. Than they nest outside, which can be a game to find eggs. Otherwise, never a problem. Love, love, love my turkeys. Have fun!!!! I'm so excited to start breeding this coming spring. Good luck.
Meet Norman and Nora. Lol
