First of all these were sold to me as "Isa Brown Pullets". As they've grown they look less and less like the red sex link girls and more like a Rhode Island Red/Production Red. Something like that. Also, I believe this one may be a rooster. S/he is soooo different from the rest. They were all born on April 6th, so 5 weeks old in this pic. Here S/he is with the group. First time having chickens.
