I have five Leghorn pullets (hopefully) that are about 3 1/2 months old. Two are a bit bigger than the rest and are developing their combs and red cheeks. I'm worried that they might be roosters. Their combs stick straight up. Do the hens flop over from the start? Or do they grow up then flop over later? I'm worried because I live in town and roosters present a noise problem and I would have to find homes for them if they are roosters.
