I have both chicken eggs and duck eggs in the hova bator. Chicken eggs go into lockdown this Thursday! I'm so excited as most of them appear good, except the ones I can't see into, shmeh. And the duck eggs are doing great too! Problem is I set all the eggs on the same day... So according to the instruction booklet, this Thursday or Friday I fill up both of the water troughs. Alrighty. Will that harm the ducks any? Also when is lockdown for ducks? Day 25? Cuz then they'll have the extra humidity before hatching time too. I'm hopefully hatching fawn and white crested runners! I can't wait! The rouens lay greenish blue eggs and I think the 5 duck eggs are brown.. Crested rouens are fine too.
