Don't know which day egg is on. Help!

[IronMan834638]

Hi all

So first off apologies for not being more knowledgeable as we are new to hatching eggs

Secondly as you can tell from the title we don't know which day are egg are on due to using a cheap Chinese incubator then transferring to a Brinsea Mini 2 Advance.

Can anyone help by judging these pictures?

Thanks in advance

Looks kinda like day 14 maybe, but don't take my word for it. You need a few others idea to be sure

I have been looking it up and comparing and I believe it is day 13=24th March. Due to the fact that it is harder to see inside but the chick doesn't take enough space to be day 14 so tomorrow I will re-candle the egg in the afternoon to see if it has taken up the space it should've done.
