They should be fine. Unless they try to join the silkie pile. Then there may be issuesI've been watching them from my kitchen window. Pompette is trying to 'hang out' with them, but they're like ahhhh! run away run away! LOL just now I watched and they allowed her to hang out a little bit before they freaked out again LOL
You think it'll be ok to remove the cage and let them sleep together tonight?

Hopefully they just create their own separate pile. My birds are much calmer at night.
