Got two Rhode Island red hens to add to my collection from a friend of a relative. I have very little information about them apart from they were hatched this year and that one of them could possibly be a rooster. They have very small crops but are larger than my other hens so I assume they are fully grown. Their behaviour is very strange compared to my other hens, when they have a little disagreement they stand tall and square up to each other and one of them occasionally jumps in the air and scrabs with her feet. Neither have feathers like a rooster but does this sound like the behaviour of a hen?
