I've been raising what I believed to be guinea hens with my chicks. The guineas are one week younger than my chicks. The guineas are about 10 weeks and the chicks are 11 weeks. I've looked up pictures of guineas, but mine don't seem to look like others I've seen. They have been given a higher protein diet, as that is what I was told to do, but still they are much smaller than the chicks. Is this normal? Thanks!!!
