aye, hybrid layers for lots of eggs, easy to keep, forget the meat. trad breeds for looks, some give reasonable egg production, also different egg colours, some also give you the option of a good size for meat. even some of the more traditional breeds are hybrids, so they get the qualities people cherish. my first birds were a mottley bunch i inherited when I moved in. they were all passed it and gave very few eggs. I moved these on to the market. I then bought some black rocks and some light sussex, who still give me eggs, after a few years. I have added , by swapping and buying, ixworths, faverolles, marans, legbars and leghorns.I now have 30 + birds who lay me a pile of multicoloured eggs every day. If I get too many birds I usually swap them with neighbours who want that particular breed for looks or egg colour.i despatch any cockerels born, and have just done a little lesson in how to best do it and process the carcass. ( was a bit reluctant to do before and wasted a lot of meat feeding the cat). there are so many breeds with excellent chareceristics that it would be impossible to give a definitive answer. maybe see what your girls like the look of and see if it works. light sussex, rhode island reds, ixworths might give you most of your needs.
