I actually think the herniated navel is going to turn out fine.
Since it was still connected in a closed system from "hatch" until 6 hrs later when it finally finally really closed off internally
(if I had messed up at the 2 hr mark when it looked closed off but was just crimped around the foot I think it would have been real trouble)
but Chick B took a long time laying around I I think it actually continued to close up so as long as it didn't draw any infective agents inside things should be good.
On the other hand I have to say, I've dealt w/ reg. & problem births in dogs, cats, goats, and llamas, and this egg hatching stuff is, for the birds (way more tricky!)
But so far B & W are doing fantastic - they can both walk really well now, and are way more active than I expected at this point, they are actually perky!
They take naps of course, but are otherwise moving around the bator, peeping to each other then finding each other and snuggling.
B has actually pecked at a few things, like little bits of eggshell. Maybe too soon to get overly hopeful but they are acting like regular chicks at this point
Zero action w/ Egg L, 15 hrs since first peep ...
