When it comes to male peas getting along it depends alot of the environment the birds are in. Free range males will squabble and chase each other around occasionally but as long as one can easily get away from the other there shouldn't be a huge prroblem. One male will take all of the hens though since they're only interested in the most dominant and strong male. The other male will keep displaying but the hens won't show to much interest in him. Peacocks don't typically actually defend the hens from predators beyond making a ton of noise to warn them of predators or threats. The two males will start getting along again once breeding season ends. I'd also keep an eye on them with the chickens, peacocks can become aggressive to and even kill chickens during the breeding season.
