It's fine to have "one of each", if they are similar sized birds. Some will be more dominant, others more submissive, but that's going to be the case whatever combination of birds and breeds you get. And if you are prepared, as it seems you are, I don't think you need to "count on" losing chicks necessarily. Of 50 my neighbor and I ordered last year, we lost not a one. And they were all pullets (except the freebie). So... I have a few LB hens. They are not very friendly, they are quite large, and while they lay regularly, their eggs are rather small, so the "feed conversion ratio" isn't as good as some other breeds. They are handsome, though, but of my 27 chickens, they are the ones I am thinking of selling to reduce the size of my flock and save a little on the really expensive organic layer I feed. Just another thought.
