I'm still a newbie at chickens, but I'm thinking some of you could tell by now what gender chickens I have. I have two RIR that are 6 to 7 weeks and two more that are about 5 weeks. Here are the 5 week olds together. The guy on the right has a red tint that has started in his comb. He is also below. This is the chick from the left--no red tint in the comb yet and better feathers. Pullet? These are the two older birds. The one on the right is feathering out faster and has red to his comb. This is the bird from the right. All of the neck feathers I'm seeing on him are rounded. He is a lapdog! This is the bird from the left. This is the climber. Hardly any color on his comb yet. I was leaning toward roo on this one, but unsure. What few neck feathers I see are rounded also. Here they are from the back--both tails are similar in size. Any ideas?
