Not sure if my hen is a roo
That looks very rooish to me! Sorry! Very pretty though!
We'll wait for others to comment...
Yeah you have two roosters for sure.
You'll probably get ALL sorts of answers as to two roosters but the basics:
It's possible they can live together peacefully forever, with one being dominant over the other but no fighting.
It's possible one might soon decide he wants to be the only roo after they have hit full sexual maturity.
Many roosters are somewhat tolerant, as long as the other roosters stays a certain distance away, they are allright but will make aggressive actions if the other is too close or he catches him breeding a hen.
The other issue you haven't asked about though- is there enough hens? Two roosters and 2 or 3 hens is too many roosters. Better have 6-10 hens per rooster, particularly if the rooster is a very frequent breeder(some are like this, others are moderate.... but some cockerels are very frequent then mellow out to moderate breeders).
Who's doing the pecking? and is it deliberate pulling out of the feathers?
with just 4 it probably is the best to pick only one rooster, but to be honest, roosters are not necessary at all so getting rid of both won't be a bad thing.
the other option is to get more girls but this has risks of its own- introducing disease, making things even more crowded etc.
Yeah it's very sad, especially for people who got them for pets or thinking all were hens...
Very sorry you have to deal with this.
There are anti- pick lotions and sprays. If you get one, apply it to that girl's tail area. The idea is to let the tail feathers grow out long enough to protected- it's the feathers that are actively growing with the plastic looking sheath around the base that's filled with protein and blood that chickens find extremely delicious. Those feathers in active growth are called "pin feathers".. some birds find them so delicious they become obsessed with hunting and pulling them out. Fully mature feathers don't have this and as result they are not so delicious... so if you can get her tail feathers to grow out, she should look good from then on.
