Hello I have 2 black sex links, 2 brown sex links, 3 barred, 2 white mystery gals all of them are about 4 months old. Then last week a friend gave me 3 chickens that are about 2 years old. 1 is a brown Sex link and I don't know the others 2 breeds. they are laying eggs every day for the most part though so they must be happy. I'm kind of worried about 1 of them her flank feathers are molting. but the skin doesn't look red or anything so I guess it's ok. Going to post a pic and see what you all think.
