I have a question............ my temp and humidity dropped and the eggs are on day 16, i know that the eggs should mostly be dark when candled but only half to 3/4 they way they should look. should i still go into lock down on day 18 or should i wait? the eggs have very active silkie babies moving but they just look a bit smaller compared to my last batch. I am at a loss here on what to do about lock down or just keep rotating till i see a pip? anyone help please need advice.
