I think the top one is a pullet, and the bottom one is probably a cockerel, though it's too early to tell for sure.
Would you guys mind giving me your opinions on these two? The top light one is 6 weeks old and giant, it did initially seem to have 3 rows to its comb but maybe not? Pretty big personality but I'm not seeing any coloring to indicate a cockerel? The bottom one is 5 weeks old and a jerk. His (?) shoulders aren't totally feathered so perhaps they will come in red? If there is anything on either that screams pullet or cockrel will you share what it is? My colored layers seem to be all turning into cockerels or have died so I'm going to be trying again on blue layers. I've read tons of posts but it's still not "obvious" to me how to tell without a bright red comb. Thanks a bunch!
