question about slow development

[candyinTX]

Hi everyone. Quick question. We are on day 13 and have 31 b antam chicken eggs. I've notices during candling that some seem to not be progressing as quickly as the others. Where some are very dense no veins visible other are very transparent with very visible veins. In both cases the chicks are very active. Anyone know what I should do.

Have you checked to make sure that temperatures are the same throughout your incubator?

Yes temp is very close looks like a few are still at day 7 but the chick is very active.

Did your eggs ever hatch? I am having the same problem but mine are shipped eggs.The eggs that were not developing as fast have all died before lock down.
