I'm looking for advice if anyone can help me, I have 6 pekin duck eggs in a brinsea mini advance which are 14 days old, they are all moving well and have lots of veins but only 2 out of the 6 have air cells, is this a problem at this stage ? My humidity is around 52% should I reduce it ? I'm nervous because this is my second batch of eggs and only 2 from the previous batch developed but then died at around this stage, I had a cheap incubator tho so assumed that was the reason .... should I be doing anything ? The eggs are on an automatic turner but they don't all turn how they should .... any advice would be appreciated
