I know this has probably already been posted, but I have 2 different batches in 1 incubator. the first batch only 1 hatched (only 5 eggs in first batch)on day 22, even after 3 were rocking on day 20. The batches are 4 days apart. I did everything to standards. Was there too much humidity in the incubator? Why did the other 2 stop and not hatch? It's obvious that there was success as I have a beautiful chick in the brooder right now, but what happened to the other 2? The second batch is on day 20, so I do not want to open up the bator if I do not have to, but I had to to get the chick into the brooder. I have read of people having success with having more than 1 batch in the bator. I candled the 2 that were rocking and they hadn't even internally pipped. THOUGHTS on why they did not hatch? Thanks in advance.
