okay so I have eggs in the bator but I started with 16 and with 2 days to go I am down to 3 eggs, here's what I need to know. I have runners, swedish mixes and pekins, all together, they cross mate and I need to know, can the runners cross with pekins? I mean they are do different in shape and build it seems like that may be sort of what went wrong with the hatch, but then this is my first duck hatch too so it could totally be my ignorance too.
