Update 10 th day. I've kept Carl partitioned next to the flock, and 2 days ago, let one of the leghorn pullets in to visit. He was terrified, but she ignored him, wanting only to eat his food and dig in his yard. I tried it with other leghorns, 2, 3 at a time, same results. Later, the d'uccle showed curiosity, so I put her in. Carl immediately did his rooster dance, and grabbed her by the neck. She shrieked, ran away, and I let her out. Well his hormones are working, I see. So I later opened his front and back gates and watched. BTW, the 2 hens were out free ranging, so it was just the 6 pullets. The leghorns all crowded in to dig up his yard, the d'uccle stayed far away, and surprisingly, the Sebright noticed him and ignored him! He stayed away from them all and it looked hopeful. So it was getting late and I let the hens in. They immediately chased him, and he was terrified. They had chased the pullets like this during integration,and it didn't seem like a big deal. The pullets were spunky, and not fazed. But Carl was in a total panic, shrieking in fear, flinging himself against the fence, and finally diving into a nest box hiding his head. All you could see was his white fluffy butt....So I scooped him up and closed him back in his pen. Sigh. We'll give him more time. When I'm at home I can put the hens out and give him more time with the pullets. And we shall see....
