I personally prefer my cockerels to my hens,yes,my hens do lay eggs which I enjoy,but all my cockerels are very handsome,very tame and I've got 5 cockerels of different breeds running with my hens.
The pro's of keeping a cockerel are 1)they do call the hens to come and eat any titbit that they've found, 2)mine also make a nest type structure for their hens to lay eggs in,3)stay with them when they are laying and chatter to the hens offering encouragement. 4)Far prettier than their wives and finally 5)have an abundance of character.
The only disadvantage is that they crow,so,if you are easily awakened you may not enjoy that part.I've stayed up all night when I can't sleep,and,my Thuringian cockerels did crow all night long in pitch black darkness.I've actually re-homed some and culled the rest.
The cockerels i've got now are pekins,serama,croad langshan,booted bantam,d'anver,yamato and a silky.They only start to crow once the dawn chorus has started and woken them up.
