Hi All, I'm new to the beautiful chicken ownership. We got almost 4 weeks ago, two Playmouth Rocks and two Buff Orpyntongs. They all seem to get along really well and they all look pretty much alike, expect one of the P. Rocks, looks slightly smaller, less white and her tail also looks different. It points down and the colors of the entire little girl are also less bright then her sister's. Am I getting paranoid? I'm really worried that are not both hens because I don't want a roos and I will need to start the process ASAP with hopefully new hens. I will hate to part with one of the them. What do you think? I have read that one can start telling at about 6 weeks, but the differences are just a bit big to ignore. Thanks for your input. Here are my two Playmouth Rocks Now you can see the difference on their tails, one points up and one points down. The one that points up also has much light color, brightness of her white while the other one less feathers and darker. Can you tell the difference or am I worried for nothing.. is it too soon to tell?
