Ok so I am a newbie, my hens are 6months old. I know this will sound bad I have three white Leghorns and three brown idk what they are! ( lol) Bought them at tractor supply! They started laying last month and now we're getting 5-6 eggs per day! Yay! Well today one of my brown ladies laid a beige egg not brown and it had a giant calcium like deposit on top and the brown chickens are much bigger than my white ones and lay bigger eggs. This egg was smaller than the Leghorn eggs. Is this something that happens from time to time. The shells are nice and hard and the whites and yolks have been perfect. Haven't cracked the odd egg yet to inspect inside of it but will in the morning. Should I be concerned?
