looks like a boy and he appears to be split to pied or white or white eye, according to those white tipped wing feathers I'd lean toward pied or WE myself. Sorry to hear you lost your whites, what happened to them?
If you had two peas die and you don't know the cause, I think you should be concerned.
It may be something that could affect this guy, too.
How long ago did they die?
*I see you have ducks and turkeys, too? It's possible these birds carry something that could be harmful to peas. Hopefully someone who knows about this will jump in here!
