for the first time ever I ordered some eggs (ebay/ showgirls)
they were supposed to come with a heat pack. well the person did not put it in.
when I got the eggs they were cold so I let them warm up(room temp)
then gave them to my girl.I candled them same night and I noticed an air bubble...
(dont know if this is posted in the right section)
anyway I love muscovies I had one a few years ago I adopted and he had something called slip wing/angel wing
it was minor and he functioned that was my first experience with it.
a few months ago I was given two Muscovy ducklings they did fine...
