That sounds pretty good, that he's not too aggressive and hopefully it'll last....none of them know what they're doing yet, they'll figure it out eventually.Indeed it was very early mating behaviour, he has now started to grab all of the girls combs, however it seems very tentative and the moment the hens screech he lets them go.
This happens maybe two or three times a day.
Maybe I missed it, but how old are these birds?
