I'm going to jump out there and say.......you know what's going to happen dont'cha?
That male bird WILL come into your life...things just have a way of working out that way.
When the urge hit me to have a pet bird once again, (5 years after a tragic loss) I ran to the petstore and bought the first bird I seen...While driving to the pet store, I decided that I knew what I wanted...a Male Lutino Cockatiel....and much to my surprise the first pet store I went to had "Hector" (the terrible name THEY gave him) for sale, Male Lutino Cockatiel.
Less then 24 hours later, I knew Hector...was most definitely NOT a male.
Chiquita is the most sweetest, gorgeous, even tempered...bless her heart little cockatiel ever! She is the one that absolutely anyone can handle, to this day, she's never bitten anyone.
Super long story short, we ended up with 4 cockatiels 2 males, 2 females...last April I lost my dear Chicken Little...

I don't talk about it because it hurts too much...we also have a green cheek and a pigeon.
Soooooo.....Who says you have to stop at 2??
As far as the egg laying...I was concerned about that too...but not enough to deter me from having hen tiels if that's what should come about. I rescued 2 tiels (a brother and sister) the female...Sweet Pea...started laying eggs about a year after we rescued her....and she kept laying...and layed some more...before it was over she had layed over 50 eggs!!! I was beginning to get concerned, but she was soo healthy, vibrant and happy...none the less I ended up on here asking for help to get her to stop because some of the eggs were starting to get soft spots. I think she layed an egg nearly every other day for almost 5 or 6 months.
I fed her a well balanced diet, free choice to calcium rich veggies plus her cuttlebone, which she used...always fresh water and I let her out daily for exercise, just like everyone else.
Just when I was getting a separate room ready for her to live in complete isolation...as was suggested here...she quit. I'm not gonna lie...I was relieved.
She's never layed like that since...every once in a while I'll find an egg on the bottom of her cage...she might lay 2 or 3 then stops. We've had her 3 years in August.
It's true, the male cockatiels are louder, learn to talk and whistle, every male tiel I've owned has developed an extensive vocabulary, BUT they didn't seem to have as stable of a personality as our females...as far as biting and in general testy behavior.
Your female cockatiel may not chirp, whistle and talk...but they CAN learn tricks, just watch youtube for tons of ideas of things you can try to teach her. And really...there is just "something" about a female tiel that melts my heart and wins me over...the look in her eye...the way she sets her head when I talk to her, her general "sweetness" ....It's not something I can explain, just a special sort of bond I know we have.
Good Luck with your beautiful babies...you truly
have chosen the right birds for you, they are quite content with you as I saw in some previous pictures. Just keep letting the relationships flow and when that male comes long...you'll know, and nothing will stop you at adding a 3rd...just trust me on this.
