Very new to the forum so apologies if I've posted this in the wrong part! In the past I've only had chickens and they have hatched their own eggs without any issues ! Now that I own a duck (female) she went broody on some of her eggs and having lost a few chickens last year I thought I would chuck a few eggs under her aswell and just see what would happen! Now exactly 21days later the duck eggs are cheeping and have a little crack in them but not much from the chook eggs some of them feel like they're moving inside although ! I'm worried the duck won't raise the chicks if they do hatch, and just curious if anyone has had any experience with this before? And also I read that duck eggs take longer to hatch? They have all been under there for the 21 days!
