I bought Peep and Nibbles (~9 weeks old) about 7 weeks ago from a local feed store. They were both suppose to be girls. They pretty much looked the same up until about a week ago. At 7 weeks of age, their combs were the same size and color, and then I went on a business trip. When I got back Peeps comb was bigger than Nibbles' was. I'm afraid Peep might be a he, not a she. Here is a picture I took of them today when I got home from work. They are still in my bathroom because we are still getting snow storms here. The second picture is of them about a week and a half, to two weeks ago. Opinions, thoughts, advice?
