I am new to chickens and have 7 in my mixed flock. I bought 2 specked sussex that were straight runs. I am thinking Ivy might be a roooster. They are only 5 weeks old so I know it's a little early to know for sure, but Ivy is my only chicken with a large comb. In the last few days it has been turning red as well. My other sussex is a runt so its really hard to compare the two. What do you think?
