I've had two Delaware roosters, and two hens. My first Delaware I got from a friend, at the time I only had one bantam rooster and they were best friends, so we named them chicken big and chicken little. He wasn't friendly, but not mean either. A raccoon ended up eating him. Then I bought 3 pullets from the store, I really wanted a rooster, but they weren't selling them. Well, one turned out to be a rooster anyway! He was the nicest chicken I had, he would follow me around, and sit in my lap to be pet. Although, I have never had a rooster that was meaner to strangers than him, he would attack everyone else who came into the barn yard! One time he wouldn't stop attacking this man, so the guy stuck his foot out to block the chicken, and he ran right into it, and broke his wing. Then he got the hugest bubble foot I have ever seen. He was pretty pitiful looking, stumbling around on one foot, and having his wing hang to the ground. So I gave him to someone that said they had the money to take him to the vet, I really missed him. The two pullets never went broody, and I don't remember ever seeing them lay an egg. I was never very impressed with the hens. Sorry, I don't know anything about how well they do in the heat.
