Ok so I've been trying to hatch duck eggs and they just constantly kept dying on me. I had 3 in the incubator but due to knowing they wouldn't make it out of despiration I went to tractor supply to get babies. I got 4 which I think are Peking. Well low and behold 3 1/2 weeks later 1 of the eggs hatched. The Peking are around 4-5 weeks old now and huge. I was wondering if and when I can put the baby in with the others to prevent loneliness. I have their pens near each other and they here one another but I feel bad. And what should I do for the baby to keep him happy until he can be with the others?
