I have a 7month female cockatiel named Sushi. And I am looking to add a baby male for a friend. I won’t start searching for a cockatiel until Sushi is 9-10 months because I have a future trip planned. I do plan on buying a baby male from a local breeder. I just want to know how will adding a young male affect Sushi. I’ve read something about laying eggs which she hasn’t layed yet. I am not interested in breeding so I do want to discourage that. Sushi has a very clingy personality and is attached to me but she’s not scared of my budgies. I just don’t want to stress sushi out by adding a young male. Please give me all the advice/ helpful tips!
