@Lilion :Manny was doing what a rooster is supposed to do! He would grab a nice piece of salad, drop it on the ground and tidbit (that little tuk, tuk, tuk) that is him calling a hen over saying 'look at this great piece of food I found for you!
Rooster's jobs are to:
protect - they should be ever watchful while he and the girls are out free-ranging - and give warning calls if something is amiss (some will even fight to their death to protect their ladies)
provide - they will tidbit when they find something good - to call the girls over and let them have it (the girls need a lot more food/energy to produce those calorie dense eggs every day)
produce offspring to carry on his line: This involves not just mating (

often!), but also helping a young hen find a suitable nesting spot and come to escort them back to the tribe after they have laid. It can also include helping parent/train/teach the young chicks (usually momma will let the rooster near them sometime around 2 weeks - but that varies drastically by hen and tribe.
Either of the first two can also include 'herding' the girls. To new areas to forage, to the dust bath area...to get them to go into the coop when it starts getting dark, and/or to keep them semi-together so he can keep a watchful eye on them all.
@BY Bob can probably add to this, as I'm sure I am missing something.
Regardless, Manny WAS manning-up when he let the girls take the salad pieces

. He was being a very good Roo!
