I do love bay chicks... but this was an experience to say the least. i had some sort of wacky problems with humidity that caused me to have to intervene with the eggs. very stressful, but id like to think i saved a lot of lives. start with 30 eggs( 20 of mine, 10 of FILS) out of his 10, 3 were not fertile.. 7 went into lockdown . Before i intervened two had already died via shrinkwrapping, one died while still absorbing yolk.. Ended up with 4 wonderful chicks out of 7 that entered lockdown. Out of my 20 eggs, 1 wasn't fertile, and one was a double yolker that i shouldn't even have tried, that quit after about 7 days. another one shouldn't have went into lockdown but i was hopeful. I think it dies day 16? it was a bantam egg that the father wasn't a bantam i believe.. so not much hope there , either... even though i really did hope. So by my count out of 15 viable eggs at lockdown, one was still way underdeveloped but was still alive. it ended up dying before coming out of the shell. Out of a grand total of 20 eggs, i got 15 babies that took 2 days of full labor.. longer than my own children. unfortunately my daughter accidentally killed one of the chicks by dropping it. I am left with 14 but 15 were successful hatches. Grand total of living chicks after hatch( I'm counting the one my daughter accidentally killed as successful) plus my father in laws eggs 19/30 starting eggs. 19/27 fertile eggs.
