My mottle pekins are about 5-6 weeks now and just checking to see whether they are girls or boys? I'm 90% sure that one of them is a girl but the other two look like boys which I really hope not otherwise they'll have to go... All of them peck at each over now and then but I don't know whether they're establishing a pecking order or not. How do I tell other than the combs? Pretty sure left is a girl but the right? Same chicken from above to the right but the bottom left is the third chook. Left and right I'm guessing are both boys because they have red combs but the middle has a really pale comb and is smaller but I'm still unsure... Just need a second opinion.
