parasite meat spots in the eggs

[playswithfowl]

I just heard about these in another post, and I was wondering they are? I ask this because my blue wyandotte hen's egg shells have rough bumps on the outside. I don't know if these are two things are totally un-related or not. Any thoughts appreciated. Here's a link th where I heard about it.

No idea what parasite meat spots are in eggs, but I know that you can get blood spots in eggs by the passing of a some of the inner lining of the chicken during the formation of the eggs. As for you dots on the shells, that is normal. Some chickens just deposit more junk on shells than others in the creation process. Not to worry.

I have no idea about this, but the way she explained it, it does make sense. If you have parasites attacking the inner lining, it sounds reasonable that it could cause a bit of the lining to break away and end up inside the egg.

I've never heard this before either, though. But it DOES sound reasonable.

ok...lets put it this way.....

There is a small chance that meat spots could be caused by parasites....
but in general..this is not the case

....the rough bumps are probably nothing but calcium deposits on the egg...

This explains the bumps...

...here is the specific reference link to worms in the eggs (which is a quite rare occurence even when the birds are infested)... I have never seen this associated with meat spots...

"....Bloodspots are caused by a rupture of one or more small blood vessels in the yolk follicle at the time of ovulation.

Meat spots have been demonstrated to be either blood spots which have changed in color, due to chemical action, or tissue sloughed off from the reproductive organs of the hen...."

scroll down for the very handy charts

...there are no worms that I know of that reside in the reproductive tract which you saw above is associated with meat spots:

4. What are the small brown spots found in the white of eggs?

These are meat spots which are pieces of tissue from the hen’s reproductive tract. Meat spots do not harm the egg. Eggs with large meat spots are removed during the grading process.
