We have 12 tetra tints from Tractor Supply. We were told that they were hens, but we also purchased a golden comet hen from them which began cocka-doodle-dooing a few days ago. Our tetra tints do not all look the same, and we are worried that we have more roos. We cannot keep the roos, and are very upset. Can someone please help us decide if we have hens or roos? There is NO information about the tetra tints that is helpful. We are new to the chicken world, and are patiently waiting on eggs. They are 4 months old. Here are some pics: Their bodies all look the same to me, and feathers too. But the (I think) combs and waddles??? are different. Some are very large and red, and some are small and pink. Thank you!!!!
