I have some of No3 - they are black rock (hybrids).  Lovely birds that lay super eggs.  No 2 looks like a black tail, another hybrid - there is also another name for them - depends where you purchase from as to what they call them!  The place I purchased my hens call these the Siston black tail as the site is in Siston!   I have 9 hybrid hens and they lay throughout the year, including all through the winter months.  They are all very friendly too and I find them so entertaining and chatty!  Love your speckled hens in the first picture.
