I got 24 chicks at TSC thinking I would about be 50-50 hens and roos. Well I only ended up with 6 roo's. I think I'll keep 2. They are Rhode Island Reds. I have two that look fine, long green tails, and are the dominant ones when they interact. The other roo's are missing tail feathers (presumably because of the two dominant ones.). Only concern is the two dominant ones have much larger combs. I am close to Pittsburgh and we get about 10 to 15 single digit to negative degree temps. Should I keep the dominant ones to help protect the gals? We do have a Great Pyrenees pup that just loves being around the chickens. Should I keep the more docile ones with the smaller combs, and just know the dog will keep them safe? Does it even really matter? Regardless, 4 of them are going to the freezer Saturday. I tried hard to re-home them with no luck.
