New broody with 2 eggs

[TANDJB]

Hi, I recently acquired a broody Silkie and the previous owner gave me the two eggs she had been sitting in but didnt tell me how long she had been on them, just said "a few days". Well I candled them and there is a very obvious development difference between the two...I was thinking one is 17-18 days along the other 6? Was hoping for some help....Oh and there is movement in both

I'd say maybe 10 days for both. Movement is a good sign. With my silkies I just give them eggs and leave them alone and wait to see what happens.
Good luck!
