I've ordered many breeds from several sources over the years, and it's true that what looks interesting 'on paper' may not work out for you. Climate matters too; hot weather breeds aren't always the same as cold weather types. Some birds don't mix well; Favorelles are sweet and beautiful, but timid in a mixed flock, and sex-links, New Hampshires, and production reds (hatchery RIRs) are pushy to a fault. Leghorn and hybrid layer types will produce the most eggs, but be more active and small for eating. Speckled Sussex hens are very friendly and beautiful (a favorite of mine!). Australorps are nice layers, and any Plymouth Rocks or Wyandottes are good dual purpose birds. Wyandottes, Black Copper Marans, and Barnfelders lay darker eggs. Easter Eggers and some others lay blue-green eggs,. and variety is fun! If you order an assortment, it's fun to figure out what you have as they grow, and some will turn out to be favorites. I do love having roosters, but it's necessary to keep one or two nice ones and eat the rest. Human aggression is NOT okay! Mary
