Ok so about 5 weeks ago, I bought some straight run chicks both RIRs, and white leghorns. I can tell the genders of the WL easily,but I'm having trouble telling on the RIRs. They all seem to look the same, and are pretty docile. Nothing about any of them 'scream' rooster to me, although my husband swears there's a rooster thats super agressive in the bunch. My question is how long did it take you before you knew what your RIRs were? Is there any tell-tale signs?
