Hello, I have two Light Brahma chicks that are two and a half weeks old. We bought them at a feed store, I believe they came from a local hatchery. They were supposed to be pullets, but I am noticing some differences in them that I am curious about. For instance, one is noticeably larger in size than the other and one seems to have a ridge on her beak. I would love to hear everyone's opinion on whether you think they are pullets or not. Here are some pictures to help... Thank you!
