Have a couple of questions.

Hey there, chicken enthusiast! It sounds like you've gathered quite the flock with your feathered friends—Sapphire Gem, Plymouth Rock, and Speckled Sussex are all delightful choices! As for the mysterious yellow ones, they could be a variety of breeds, potentially including those speedy Cornish Crosses you mentioned. Since they’re growing at the same pace as your other chicks, it’s a fun mystery to unravel! Now, when it comes to identifying any roosters in your crew, keep an eye out for those telltale features like comb size and behavior. Even if you end up with all hens, that’s no problem at all; each chicken brings its own cluck-tastic charm to the flock! Happy chicken-keeping!
