Crevecoeur - Egg Laying Problem

[Heritage Hens]

I have only one Crevie hen. Hopefully I will have at least one pullet in the two eggs that I successfully incubated from her.

From only six eggs total from her ( she just turned pullet), only these two were viable. But, after a week or more of not laying, she layed one egg that had a paper thin shell and it broke in handling it. Then she layed a larger whitish egg that I could tell was a cross with an Orpington rooster. I destroyed that egg.

Do you think a young Crevie hen can be damaged by producing a large, regular sized chicken egg? I am worried about her internal structure having been injured.

Since then I have confined her to a room with my best Crevecoeur cock and she has layed one normal looking white egg. After over a week long hiatus.

Wondering if others have problems when there are non-Crevie roosters crossing with Crevie hen.

How could you tell by looking at the egg it was crossed with an Orpington?

Sometimes you can't if the hen was an Orpington and the roo a Crevie.
If my Crevie hen lays one, it is a little larger than usual and not completely white.
I have had these cross-chicks hatch from both. 3 of them.
Let me tell you that these chicks are ugly. They have the body of the Orpington chicks, but the feather cap of the Crevecoeur.
I gave them away as pets to a family that would give them a good home.

Since your pullet just started laying, you can expect some oddly shaped and over-sized eggs now and again. The size and shape of the egg is no indication of what sperm is inside of it, so I would not use that as a method of determining parentage of any potential offspring. She should be fine after laying the abnormal eggs. Remember, if she has been exposed to a rooster of another breed, you'd best wait at least three weeks before saving any of hers to hatch. That way you can be sure none of the other rooster's "influence" is still coming out in the eggs laid.

x2 what OldChurchEggery1 said

Your pullet is probably just "working out the kinks" as a new layer. Hens also may lay odd eggs every once in a while...lighter,darker, larger, smaller etc. throughout their life. If you continue to get thin shelled eggs, she may need more calcium in her diet.

 

[NYREDS]

The sperm does not influence either the size or tho colour of the egg. There is no way, by looking at an egg, to tell what male fertilized the egg. As others have said a pullet will sometimes lay an unusually large, or small egg. Egg colour is determined solely by the genetics of the female.

Well, this is good information since I am not experienced with this breed. I have given her chopped hard boiled eggs and she has free range to sunlight by herself and her mate.
At least I have two more in the incubator and two healthy chicks in the brooder.
