We got some fertile eggs from a friend for our broody Buff Orp to hatch out. He put two duck eggs in the carton...now we have 10 chicken eggs and 2 Apple..something or another duck eggs under this hen. Eggs have been under her for 7 days and she's being a very protective mom. What do I need to do when these chicks hatch on day 21? Someone suggested taking all the chicks out and maybe the hen would sit out another 7 days on the 2 duck eggs. I'd rather pull the duck eggs on day 21 and put them in an incubator if possible. Your thoughts on this please. Anyone ever done this before. We aren't keeping any of these babies but I'd hate to sacrifice these two ducks on day 21. TIA for your help and advice!!
