We bought some straight run chicks from a man who had a little family owned flock. We picked them ourselves at 3 and 4 weeks old. They are now between 4 and 5.5 weeks old. They're mostly mutts (parents are standards, but these are all crosses other than the RIRs as far as we know). We didn't care too much as long as they'd handle some chilly winter nights and give us eggs. Several have pink in the combs... does that always mean it's a roo? #1. Buff orp. (?) Our little bully... He's bigger and even has red on the wattles, too. #2 We call it Hedwig and love it because it is sweet and doesn't mind being held. Smaller comb, but has wattles and there's definitely pink in the comb. white orpxleghorn (I think) #3 RIR... We have three like this one. This one is feathering out slowly, but grew its comb over night. #4 RIR The only one we have hope is a hen... tiny comb, smaller body, and nearly fully feathered out. #5 BR cross. Some red in the comb and wattles, but this one is smaller than our other BRx chick and has a much smaller comb. #6 Our other BRx. Comb got really big in a single day and is now getting pink. #7 Our third RIR. I'll post a pic of #8 tonight. No one wants 6 of 8 chicks to be roos, but know it happens. We're wondering if we should wait or if we should get ourselves a few that are sexed gals to make sure we end up with 4 hens.
