Hatch B was started with 24 eggs and 10 were fertile.
Also, it seems that fertility is not what it used to be. On my third batch, Hatch C, of the 19 eggs set, 4 were fertile.
My assumption is that since they are in a new location and I am unable to have a pool of water in with them 24/7, that could be hindering fertility. They get access to a pool every third or fourth day. Also, some of my pairs are older now.
On the incubating side of things, we had a major storm roll through and we had a power outage for 2 days. My husband had a hard time finding one of our generators that actually worked.
It's always a gamble with incubating, but it still is fun!
