Yes and at the moment some of them are externally pipping they are being sat on by my Mascovy my cayuga was sitting on them but she was not a very good mum so I put them under the Mascovy its my first time having ducks and I can not wait until the ducklings hatch one started to pip externally last night and the rest just copied i am pretty sure about 7-8 out of 11 should hatch I can't wait
