Norfolk grey incubations??

[Chickiemummy1]

Hi all ive recently been incubating mille fleur bantam eggs from my own chickens (in with a male ofcourse) and had some live fertilised norfolk grey eggs given to me for incubation. All my mille fleur eggs are doing perfect in my incubator however, 4 out of 7 of the norfolk grey eggs have blood ringed on me 3 during the first 2-3 days of incubation and one during day 13-14 ive tried looking on the internet about any issues that could come from incubating norfolk grey eggs but came up blank... Any help would be greatly appreciated!

Hi, welcome to BYC!

What are Norfolk Grey? Are the chickens? Were they shipped?

Here is a fantastic resource for hatching. If you scroll to about page 50 there is detailed cause of embryonic mortality. Though this is meant for chicks....

Hope this is helpful.

Happy hatching!
