I have 3 chicks that I believe are the same breed and are within a day of each others hatching (3 weeks old). Not sure what they are and they all seem to have different combs coming in already. They all have feathers on their feet, two have black feet with one white toe and the other has all white feet. Any thoughts on breed and if any clear signs on gender would be great! Thanks!!! This one above has a dimple at the top of its comb.
