Late death in eggs

[waibel zoo]

What causes this? I had 2 hatch today. 3 did not. I candled, no movement or anything. The veins were starting to dissappear. So I pipped them. All 3 were dead. THey were alive when I put them in the hatcher on day 18. What causes this? The other 2 are fine and stumbling around.

Too high of humidity can kill them.

Some are just weak and don't survive.

This same thing happens to me everytime, shipped eggs and non-shipped. Each time I try something different. I really don't know what else to do. This is my 4th batch, I finally decided to open a few just incase and they were fully formed and ready to come out.

What are your temps running? Are you keeping a log of temp/humidity so you can review what's going in in your bator? That might help narrow it down.

Are the air holes open on the hatcher? Fresh air is important when hatching. Other than that, humidity vould be the cause.

I have two incubators. One I use for incubating, one for hatching. The incubator one is a hova-bator still air with an automatic turner. I keep the humididity at 40-50% and the temp at 100-101. I leave the plugs out, always. The hatcher incubator is a turn-x forced air. I keep the humidity 60-65% and temp 99-100. It does not have plugs. I did calibrate the thermometers and teh hygrometers before I started. When I open, they look moist,and seem to have theappropriate size air space. I check my humidity and temps like 5 times a day. I occasionally make adjustments, like when they start to make their own heat. I have never had spikes over 102. And temps have never dropped below 99.

When it happens repeatedly it's something but what is a tough thing to nail down.

If it's your own stock you need to figure out if something genetic is going on.

Re-sanitize the lyon just in case.

If it always happens in the Lyon you may want to rethink that as a hatcher. Maybe yours has clogged holes or something you can't see. I dunno, I don't have one to look at so I cant trouble shoot it.

Usually the last few days is either humidity or ventilation. If I were you I'd drop your hatcher humidity down to the same as your incubator - they were doing fine in that range before the transfer... maybe your area should have a lower RH than normal. If your numbers go up - that sucker is your problem.

What is RH? Would altitude have something to do with it? I am nearly at 5000 ft. I disinfected the lyon each time I hatch.

So the few that you opened, did any make it?

You're at high altitude - there's less air in your air! I used to live at over 8000ft. Stop using the Lyon, no way it's allowing for enough oxygen exchange for that altitude - I'd be tempted to use the Hova and an extra fan in it and hope. It is probably altitude as much as anything. Drop your humidity more slowly say 50 for the next hatch, and try an extra fan.

See if your numbers improve. There's a reason they don't like women to have birth at high altitudes - all that work, all that little air.
