Thanks WKAmy & PeepsCA!
All very fascinating with these little whizzers... As of today, they can fly! Have some 2x4in fencing over the top of the lg stock tank they're in. The tank is at least 2 ft tall sides, & when I took the top off to feed/water/clean today, the little whizzes just flew up to the top & hopped onto the windo edge to look outside.... they were EVERYWHERE, Lol. Have them in an enclosed 4 season porch on the north side of the house, with heatlamp suspended over one end of their tank. Its a 14x14 ft room, or so. At least they couldn't take off running for the hinterlands! Think they might have tried, given the opportunity.
The little cuties were mostly in a flock, peering out at me from under the shelf, while a number of the others happily perched on the low metal shelf in the pics above, contentedly watching the fray & alternatively gazing out the window. Caught 'em, cleaned their toes off again, & put them back in the COVERED tank! Need to find a nice mirror for them to admire their cute little selves in...
Per the info from Strombergs, they hatched out at about 10am 7/17... they certainly seemed far more developed & competent than chicks, initially. I'm really happy about what I received -- its particularly interesting to see them start to feather. Currently using some stockpiled puppy pads in the tank. Would be nice to put them on something less messy, as even in 1 day's time, its stinky & nasty. Just can't stand letting any of the critters be in filthy conditions! Even the cattle have a straw bedded barn FAR cleaner than most, from what I've seen, and acres of nice grassy pasture. Have newspaper layers under the puppy pads. Seems to help in cleaning it out, it rolls up well with the newspaper under, & I don't HAVE to take keets out while changing the 4 puppy pads.
Looks like both of you have some really nice outside runs! Do you have a double door system to keep them in? As fast as they move, seems they'd bolt for the door & head for the hills - yikes!
