My muscovy is setting on 2 eggs. We are on day 23 ....I candled..One egg I could clearly see veins a black mass about 1/3 of egg and movement! The other egg looked 1/2 empty and 1/2 dark. I saw a dark small ring,,,nothing blood colored and nothing moving and it seemed a little liquidy (I did not shake it!). What do you think , possibly good or dud?
