Ok...so I've resigned myself to the fact that these are probably Roosters (first time chicken owner, 25 assorted straight run from McMurray...of which I think I'm CURSED with 80% Roos...) All 3.5 weeks old. Red combs and red wattles coming in on a bunch of chicks now (the giant Dixie Rainbow was first with a real wattle at 2 weeks, 6 days!) What breed do you think this is? And this? (Wondering about maybe Brown Leghorn?) Thanks! More to come soon!
