the questions are asked, your answers are vague.
feathers missing. from where ? haw many ?
two roosters are not that many for 16 hens.
I have 5 roosters with 6 hens, I did have about 25 hens but I am selling all of them.
one rooster is dominant. the other 4 roosters go after the hens, but only if he isn't around. which is just about never.
why do you have roosters anyway ?
you don't need them for egg production,
and from what I have gathered from reading,, you are not breeding them..
