Are the head stripes wide in the center with thin outer stripes? Or all thin broken/squiggly stripes? Wide = Buff Dundotte, Broken/Squiggly = Buff. Cute hatch
Congrats!!!
Sorry you lost a keet from this hatch, sometimes it's just not meant to be. Might have not developed a strong enough heart or lungs, it's hard to say.
I've never experienced a blind keet, but going by your explanation, it does sound like it's either blind or has some type of neurological issues going on. I'm surprised it's made it to 2 weeks of age... is it eating and drinking ok? If it's having issues now, IMO it will never be able to free range and fend or itself... and as hard as it is to think about doing the deed, you may need to put it down, unless you want to deal with a "special needs" bird it's entire life. Sorry
Edit:
PS... If you catch those lil buggers and put them in a smaller box or a bucket for a Photo Op, you can usually get good pics that way and can zoom in on their heads to see the markings. They hate it, but they get over it, since it's just temporary, lol.
