Fry Raising Questions from another newbie... Can't Post

Currently, I have 2 fry, about 1 1/5 inches in length, & about 4 weeks old. I have lots of questions & this site has been the best one I've found & really helped us new koi-humans with these wonderful new family members. I have a few questions about the babies, & hope someone can provide some insight.

1. Approx when should one be able to see barbells? We have one male sarasa & 4 koi (2 male, 2 female) We know who "mom" is, as she was a new addition, & the other female had spawned earlier this season. But with 3 males, there's no telling who papa could be! Any ideas? I attempted to take some pictures, but couldn't get a clear shot.

2. When should you start to see colors? One baby has very distinct black on its back; the other is still white-ish, with maybe a little bit of a flesh coloration (hard to tell when they're in green water). I've read in a few other threads here that you can tell from the coloration sometimes what the babies are (koi or mixes), but no one's been real specific about this!

3. What size or age would the babies be safe to put in the pond? We have 2 10-12' koi, the rest are around the 6' mark or so, plus random bullfrogs who have found us- I'd hate to spend all this time raising the fry, only to have them eaten!

4. Should I winter them inside, in an indoor pond? They probably wouldn't be real big by the time the colder weather hits us (Good ol' Kentucky weather).

5. When would it be appropriate to begin feeding crushed up regular food? We've been feeding them baby brine shrimp, liquid fry food (they're big enough now we stopped giving them this) & "first bites", as well as the natural algae that's been growing in their tank. I was able to find some spiralena (finally), but would love to crush up some "growth" formula food for them, but don't want to do this too early & lose them.

Phew... I think that's it for now! Thank you all so much for any help, assistance or wisdom you can share.

I began feeding our fry powdered high protein pellets at 2 weeks, so you should be fine to start doing that. Since they are at 1 1/2" length they can also feed on small worms and crushed shrimp. You can even teach them to eat from your hand with the shrimp, as it is too tempting for them to resist.
As far as putting them in the pond with the rest is concerned, you obviously have very young Koi judging by their size, so I would let them grow another inch before placing them in the pond. Juvenile Koi will eat small fry, adults don't.
The barbels won't become very evident until they are a bit bigger, I'd say around 3-4" they should be easy to see.
How much color (if any) they develop boils down to genetics, and that is always a crap-shoot in an uncontrolled spawn. You'll just have to wait and see.
For a time progression of fry development take a look at my recent postings here.
