6 days early!!!! i was so surprised! he looks and acts fine... will he be ok?
the other eggs arent ready to hatch (but look like they only have 3 moredays!)
For a chick to hatch six whole days early I think it must have been accidentally incubated for a while prior to your setting it in your bator. I can't think of any other explanation unless it isn't a chicken egg at all but some other type of bird with a shorter incubation period...
