This is a sample of 19 hatched around May 31st. They are all a variation of these little ones. Some black bills, some black legs. some are showing barred. What crosses would you guess?
Looks like you may have some Barred Rocks, Black Australorps or maybe even some Silver Laced Wyandottes. You might want to post these pics in our What Breed section for more help with this...
Hello and Welcome To BYC! X3 on try the What Breed/Gender forum, for mixes especially they are still pretty young for the best guesses, you'll probably have to wait until they are about grown and have their adult coloring/ feathers.
That neighbor I got the eggs from has a very dark feathered flock. There are some austalorps, jersey giants and some cuckoo marans and just now I saw a silver laced wyandotte
