So I'm buying three silkies from a woman on Saturday who breeds them, and she said that it is not guaranteed I will get all hens (which is what I want). I have two chickens at the moment, but I used to have five, three of which were polish, which were SUPPOSED to come sexed from the hatchery I got them from, but they ALL turned out to be roos I personally get really attached to all my animals, especially my chickens because I think of them as my babies since I raised them from birth practically, so I was extremely upset. I am still worried that my silkie may be a roo because she is only 4 months old, and you can only be sure when they are about 6 months old. Any who, the lady that I am buying them from told me that I could always purchase this "no crow" necklace her friend makes and sells, because it goes around their neck, and must put pressure somewhere to make it so they can't crow.They can still breathe fine, and make some noises, but not nearly as much. Has anyone every heard about these/know if they actually work? The lady seems really nice, but I am having a hard time believing her! I have already gotten rid of three of my babies, and I certainly DON'T want to have to give up another!!! Also, if I did get and keep the roo and buy the necklace, Would the roo fertilize the eggs? Or is there a way I could stop him maybe. Thoughts? Ideas? Thanks!!!!
