Yes, #1 is a definite cockerel. And I strongly suspect #2 is a cockerel as well-- clear photos of the feathers on its back and wings could help confirm. The two silver/whites, #3 and #4, are pullets.UPDATE:
Recent photos of the 4 chicks. 1 is defenitly a rooster as he starts to try and make noise in the morning...unsure which one but my guess its the first one! View attachment 1498920 View attachment 1498927 View attachment 1498928 View attachment 1498929
