I need some help I.D.ing these chickens I inherited from my dad after my mom passed away and he didn’t want them any more. (they was always her thing not his) the only thing that he remembered about them was that they were #1 bought at a local farm & home store here on “one of those ‘chick days’ things.” and #2 they were supposed to be good “dual purpose” birds, and that they was all supposed to be the same breed. I can tell you that the eggs are brown, and the skin looks white (the birds are not all that tame and will not as of yet let me catch them. Also the photos don’t really show it well but the iridescent green that is on the roos tail fathers is also in the hens back fathers. Also although i started out taking the birds to honor my mom’s wishes that they be taken care of, (I have since grown to like the little gals a lot and even bought a couple new ones from the chick days this past weekend) I have been doing a lot of research and this Marek's disease has me scared. Though none of the birds show any issues. The land that I have my brand new coop/run built on has never had any chickens on it at all, though my neighbor has had some in the past less than 100 yds away from my coop. I am worried about bringing her flock into the new pin,since everywhere says once infected always infected, and bringing Marek's to my land or the reverse bringing them and the neighbor old flock having infected the land any help on how to tell if they have it/if the land has it would be VERY appreciated. thank you.
