We have 3 different breeds of chicken. They all get along with each other.
The White Sussex. The Sussex chicken is a dual purpose breed of chicken that originated in England around the time of the Roman conquest of Britain in AD 43 that is a popular garden chicken in many countries. It lays about 250eggs a year.
The Bluebell. The blue-slate coloured Bluebells are one of the biggest of the hybrids and also one of the most popular. They are derived from various types of Marans Coucou and Rhode Island Red. They can come in light slate grey or darker grey shades. They have a large red comb and black feet. It lays about 260eggs a year.
The Barred Rock. The Barred Rock is a hybrid derived by crossing a Barred Plymouth Rock (cock) and a Rhode Island Red (hen). It gets the bars (attractive black & grey stripes) in its feathers from the Barred Plymouth Rock which gives it a very attractive plumage. It’s a reverse cross of the Black Rock and like the Black Rock it is a reliable and tough bird. It can lay up to 290eggs a year.
