Yesterday Addy came in with a strange egg.
Strange eggs are not really that unusual. When you have 31 laying hens, there is bound to be an odd one in there every now and then. We’ve had two shell-less eggs, a fart egg, speckled eggs, and eggs with large calcium lumps on them. All are considered to be normal (if it only happens once in awhile) in the life of a laying hen. Hey, when you are laying an egg roughly every other day, defects are bound to happen.
It’s important to keep an eye on your hens’ eggs though. Too many calcium deposits might mean that there is too much calcium in the diet, it’s time to cut back. Weak shells? If you get them more than just occasionally you’d probably want to add more calcium (we use oyster shell.) Speckled eggs? Enjoy their diversity.
But this one was different.
“Mom, you’ve got to see this egg,” said Addy coming up the stairs. She showed me the egg she had just collected from the henhouse. It didn’t look all that strange, sure it was a bit larger than others but not significantly so. Addy then turned the egg sideways.
Ah, that’s what was so strange about it. It was completely flat on one side. Not only was it flat but it looked like the bottom of the egg was puckered, like someone had stitched the bottom on. It was a large misshaped egg and in some ways, was very cool looking.
Here’s a quick little anatomy lesson. Chickens have a large ovary from which an egg (just the yolk) is released roughly once every 18 hours. As the yolk travels through the long and twisty oviduct (it sort of looks like a small intestine the way is bends around) the albumen or white of the egg is added. As the egg travels further, the calcium rich shell is then added right before it leaves the hen through the cloaca.
When an egg has something wrong with it, depending on what is wrong, you can figure out where the error occurred. For example, if there are two yolks, that means that either two eggs were released from the ovary at the same time or one yolk was released and it didn’t travel far before another yolk was released.
If there are problems with the shell, you know that something in the roughly last fourth of the oviduct went wrong.
In this case, I’m not sure that anything actually went wrong. The coating was complete, it’s just that for whatever reason, when the shell was applied, it created a flat side. Not dangerous to the bird but certainly interesting enough for a young girl to bring it up to her mother’s office for a look-see.
As the shell was intact and appeared to be strong (it didn’t crush when I applied direct pressure) I’ve chalked it up to “one of those things.” A flat egg is not cause for alarm but it certainly does mean that we’ll be monitoring the egg situation a little closer for the next few days.
