If he only watches carefully as you handle the hens and if you keep calm and keep the hen calm and put her back down...he'll know you're not hurting them and will probably accept it without attack. I handle my hens regularly, pick them up keeping everyone calm and putting them back down pretty after just a few minutes, in front of the rooster and he keeps watch but accepts it without too much concern. Works for me, but keep your eyes peeled and a check on your emotions around him.
