If it was more than one snake without eyes, I'd for sure not breed that pair together again.
I've never dealt with any snake with no eyes..."special needs" may survive as pets OK since they rely on scent & heat, but seeing motion sure helps them...I dunno
what I'd do, I'm glad I never had to decide.(I had one parthenogenetically-produced rosy boa some years back, with one eye & other defects that I kept until
she passed at 8 mos. of suspected internal irregularities, but up until that time, she ate & shed well...I was rooting for her, 'cause I'm a "chump" I guess? And
incidentally, that's how I got into breeding rosy boas for 5 years...I didn't want that female to produce more such babies that broke my heart. When she had a
mate, she made very robust & feisty neonates with no defects whatsoever.) Good luck with your decision...
