This spring I want to do an experiment. I want to hatch both some chicks in my LG bator. I have had very poor hatches before due to many factors and want to do it right and sucessful. However, the main reason for this "experiment" is to see the difference in temperment and friendliness between chicks gotten as week olds and chicks I hatch myself. I want to stick two or three of my blue swed eggs in there and try the same experiment with ducklings, but I have read you shouldn't hatch the two together. I'm not sure why though. Would staggering the hatch dates, putting the chicken eggs in and then 3-4 days later putting in the duck eggs, solve the problem? In my manuel both have the same temp. suggestions and both incubate app. 21 days. Is there any way to do both together? I don't want to run the bator a second time after hatching the chicks, because then the ducks and chicks can't be in the same brooder and it will be hard to deal with.
