I set my eggs on Sat Feb. 4th so I am counting today as day 21. One egg started rocking a lot on the 21st(day 17) and the 22nd, but then hasn't had much movement since, it did start some very faint chirping on the 23rd and more yesterday but now it is quiet and still. If they are chirping does that mean they have pipped internally? and if so how long can they survive before an external pip? at some point yesterday it must have had a good wiggle because the egg turned 45 degrees. Trying to be patient, and not worry but its hard!!!
