Roosters take care of their girls and keep them from nasty predators outside the coop. Inside the coop, my roosters are very attentive to the girls, and protect them while they lay their eggs. One even layed down on an egg until the next hen came to lay her egg, as if to give the hen a break from tending the eggs, or perhaps to keep it protected?! Anyway, he was quick to let the next hen in the nest to lay her egg.
I pick up our roosters and give them attention just as I do the girls. The Lt. brahma rooster was already tame when he came to us, and is nothing but a big sweet baby who loves to be held and loved. The other one was hen raised and so was a little more wild, but he is coming around and is getting used to the attention.
The roosters will pick up bits of food and bring them to their "ladies", I just saw this again today when I was giving them some sprouted wheat. They took it from me, and carried it to them. I also saw the younger, thus smaller rooster gently take a piece of wheat grass from the beak of the bigger one, and in turn go give it to his "girl". The bigger one thought nothing of it, and just went to get another one to give to his "girl" I think possibly it may be how they were/are handled when they are young.
