I have 7 chickens were told they were all hens but as it turns out I have at least 2 cocks and maybe a third. they are about 16 weeks old they are a cross between ISA browns and Americana which should lay green eggs. Got these from my cousin who has been having chickens for about 10 years or so he sell eggs so unless he played a trick on me to get rid of his cocks something went wrong. so I am trying to find out if hens at the same way as the cocks at this age by puffing up their necks and fighting. If anyone wants the cocks just say so.
