Hi everyone, I'm thinking about picking up some chicks and am only allowed hens. Someone has a group of mixed chicks and I'm trying to only pick out the girls. Most are pretty clear which are females and which are males. But these two I'm not sure. I'm thinking the RIR is female and the BR male, anyone with more experience then me have thoughts on this? Anything for me to look for in person (they'll be 6 weeks old by the time i pick them up) because I can make a decision when I'm there in person. Thanks!
