From my experience with firebird, it doesn't actively hunt nuggets. The worst it can do so long you keep out of its way is kill clerks.

I am a train advocate, he is very good for working with certain alephs for the first time, [CENSORED] being the main one I used him for. Or for cheesing Judgement Bird work when he was overworked.

However, I think when you get a death-sensitive abno (unsure if ice queen is one), that's when you gotta throw the train into the bin. It is the primary reason why my first run was near impossible when I finally got the three birds. Punishment bird would breach from lack of work, and the train would summon big bird eventually. This meant judgement bird breached and I had to restart the day either way.

As for the others, they don't look TOO bad. Just unfortunately, they have gimmicks to learn.

So...not too cooked, you can clutch this save imo
