Diagnosis for spots on egg

[MysteryChicken]

Can calcium deposits show up suddenly at day 14? All the eggs were normal and smooth with no spots when they were laid and these spots didn't show up until yesterday.

No, they had to of been there the whole time. They can't just appear after awhile.

just don't understand what these sudden appearing dots are.

Me neither, will be curious to what might show up during and/or after hatch.

Greetings everyone!

My name is Jason and I'm new here. I have a small backyard flock of silkies and one of the hens went broody 14 days ago. I noticed she may be rejecting this egg because the past 2 days I have found it cool to the touch and at the edge of the nest. It has formed this external ring of very rough red dots around the outside of the egg. The dots are very small, rough to the touch, and go around the egg long wise. I have candled the egg and the embryo is moving and internally things seem normal. It is 14 days now into the incubation by broody hen. Does anyone know what this is ? Any insight would be greatly appreciated!

Edit: All of the eggs that were set with this hen were normal when laid and the spots on this egg only developed in the past 2 days.

Thanks,
Jason

Update on 1/10:

The hen never rejected the egg like I thought she was and it seems it is developing normally. My hypothesis is that as the embryo developed, it caused increased pressure on the the membrane and a blood vessel ruptured and seeped through the shell which is why that ring of red dots formed around the egg. I know that isn't normal, but if it were just one vessel then the other vessels should be able to compensate. I'll update again this weekend. Eggs should hatch Thursday or Friday.

You all! It's mites! I can see them on the egg and hen's tail feathers now.. Now I have to deal with that immediately because hatch date is tomorrow or Friday.

That had crossed my mind, figured it had to be external.
Go ahead and dust the broody, the nest, and new nest bedding with permethrin.

Done! Thanks! Now we know what a mite infested nest might make a egg look like!

Wonders why only one egg shows so much gunk?

I noticed a little bit on another egg yesterday too. Great news is the mites that were visible on the hen died quick after the dusting. The first chick just hatched about an hour ago and all seems well.
