don't know what breed they are ! they have been in a cage (seperated) don't know how old??
we inherited 3 when we bought our farm .. then one more that is in with the hens.
you'd have to try it to know.. every individual is different. first one looks like a australorp i once saw (though it could be anything) second (black and silver guy) is a EE. other 2 pictures are rhode island reds.. rhode island reds are known for being bullies so they could cause trouble
