The first egg that started hatching is now looking like it might be the last, it started on day 21 it's now the morning of day 23 it's made little progress, my incubator doesn't have a humidity read out but I've done what it says to do in the instruction booklet. Already two chicks have fully emerged and this morning one egg was almost halfway out and 2 more had piped. How long should I wait before I try helping this chick? It's getting a bit bashed about by the other chicks at the moment.
