Eggs that become cold die,Is your roo fertile? (everyones question), when it comes to hens are there to many for the roo to handle?
Duds are inevitable! Could be from weak embryos, may of started to develop then stopped and died, could be a genetic weakness in the parents, or from poor humidity, temperature, that's to hot or cold.
What do you mean duds? Like the eggs are duds because they aren't producing chicks? Or did you mean dudes? If is the first one, you probably need to have both male and female chickens, egg hatching and laying takes time. If its the latter I'm not sure what you want as an answer.
