So, out of 27 shipped eggs from FL to TN, all but 6 show signs of development today at 3.5 days in. That is a reasonable amount - my own eggs have about a 10% failure to develop straight from the hen to the incubator. I feel like if the shipped eggs at least START, the sender did a good job, and the rest is up to me, the incubator, and sheer luck.
I'm leaving those 6 eggs in the incubator until Day 7, though, just in case my candling missed something.
I don't purchase live birds, I only hatch my flocks. SO I have been purchasing eggs shipped for many years. SOme will hatch, some won't. But it helps you develop ways to pack your eggs, help the shipper pack their eggs better, etc. I buy eggs for big bucks as I keep very high quality birds and cull heavily. I ship eggs and tell customers that they should have a 50% or higher hatch rate if the post office does its job and their incubators do theirs.
You have to consider the post office, your incubator, weather, and other mishaps a long the way.
I have had a few batches of shipped eggs even as far as TN to CA with hatch rates 80% to 50% most of the low hatches were probally my fault, low humidity, incubator temp spike. I have 41 eggs in right now all growing, culled about 10 after a week that were not growing. We will see what happens.
Out of 12 I only got three,out of 16 three hatched,I do a little better with silkie eggs that are shipped,myabe 40 percent.But when you can`t get chicks or adults of the breed you want its all you have for an option
For me 0% to 68% but I only started getting shipped eggs this year. The batch I have in the incubator right now I just candled on day 15 and out of 15 sent 12 are moving and active. If they all hatch that will be an 80% hatch rate.
14 royal palm eggs shipped to me only two were developing but one made it to day 28 and died but the seller said she would send me more when the weather cools but we will see if they fall through.
