بسم الله الرحمن الرحيم
(Fatwa: 161/118/D=02/1435)
The conditions of aqiqah are just like Qurbani, e.g. goat of one year and buffalo of two years. The animal should be healthy, not blind, one-eyed and lame that may not walk on foot to the slaughtering place, etc. In short, an animal whose qurbani is lawful its aqiqah is also lawful.
Allah knows Best!
