Oldest eggs hatched?

[LongRanch]

Just wondering if anyone has tried hatching old eggs? I bought some chicks from a lady who was moving and had to sell all of her chickens. As such, she also could no longer keep any of her hatching eggs either. She threw in 18 hatching eggs for free. I already had a homemade incubator going but it was full. I immediately ordered a Hova Bator but it didn't get here until yesterday. She told me the eggs were under a week old, but couldn't be specific... That was 2.5 weeks ago. So the eggs are probably all over 3 weeks old. I threw them in the incubator anyways, since I certainly have nothing to lose! Think any will hatch? I will keep everyone posted. They are several polish, one show girl (she said probably naked neck), and several olive eggers.

A while back I found one of my guinea's nests. It had 57 eggs in it, if I recall correctly...all from the same bird. I took 43 from the top and put them in the incubator. 30 developed but only 9 made it all the way to hatch. I assume that the 9 that hatched were 9 of the freshest. However, these eggs were out in the brush, exposed to dirt, mud, sun, rain, temperature fluctuations, and such.
