I have to admit, I am quite addicted to sexing chickens by appearances. I am not into feather sexing day olds, or vent sexing - as I breed my own birds and feather sexing is very precise. You have to keep two lines of chickens, using fast feathering males and slow feathering females. Since I have no idea how to determine if the birds I presently have are fast feathering or slow feathering, I'll stick with the visual sexing guides only Also, vent sexing.. Just don't feel comfortable with it personally. Comb Sexing: click to enlarge Single combs (note wattle buds in 3 week old male to the right) Males pink up early, where females often times stay peachy until they are older. click to enlarge click to enlarge Leg Width: click to enlarge Leg Width Sexing does not work for all breeds.. Naked Necks are especially easy to sex this way (at least my line). Colour Sexing click to enlarge click to enlarge If you are buying birds over 12 weeks at a sale, check out these very clear differences between mature cockerels and pullets: click to enlarge (Note: Not all hens will have 'small' combs, but they will always almost always be smaller than the rooster's.) click to enlarge Sexing crested breeds such as Houdans and Polish can be done later on by their crests if you can not yet see the cockerel's pointy saddle/hackle feathers. By 12 weeks old the crest is noticeably different between the two sexes. Cockerels look like rock stars and pullets have a round afro. click to enlarge Silkie sexing.. One of the hardest breed to sex. Especially for those new to the breed. The roosters aren't always clear and sexing tips I have given you previously won't always apply. Often times males have very tiny combs. Not much larger than a pullet. Their hackles and saddles are longer - but not always obvious to someone buying a Silkie for the first time. The biggest give away that you have a cock bird is by their crest.. Males have whisps of feathers coming out of their crest. I find the males look like they have mullets - business in the front, party in the back. I hope this helps you in your sexing attempts. If anyone has any clear pictures of breeds that can be colour sexed that I have not already included in this post, and would like me to edit and share in this article, I'd be grateful. I would love to have a collection of images for others to reference back to when trying to sex their own birds, or trying to help others. Feel free to repost any of these images so long as they are not edited in any way.
