In the past I had two zebra finches and a number of society finches. My two zebras.. Pip and Squeak.. were male and female, and in the same cage together exclusively. I was young so I don't remember all the details.. but I know Squeak never laid a single egg all her life. Maybe this was abnormal?
Today I am married and we got ourselves a canary. He's not very good at singing, but we love him all the same. Every morning I chop up kale and broccoli for him. Sometimes spinach, sometimes carrot. Sometimes other veggies I have in the fridge. It gets mixed into his seed. He lives in our dining room where he can watch us when we have dinner and watch tv and whatnot. He sings to us (badly, lol) whenever we're around... but the problem is that we're gone alot. We both work.. our hours are long and we're gone nearly 10 hours each day. Poor little canary all by himself, we thought.

Raven (the canary) and Tap (the green singer) got along almost instantly. Tap sings very prettily, and Raven still sings.. badly, lol! But we love them both. ....and over time we found out that Tap is a female. She laid an egg in their food dish.
I wasn't sure what to do.. the egg ended up cracked somehow so I took it out. I felt bad about it but it would have gone rotten and I knew it couldn't be fertilized anyway. Besides.. she was constantly sitting in the food bowl on all the damp veggies.. her belly feathers weren't looking overly nice. I was afraid she'd damage her skin or go bald there. So I took out the egg and we switched to a smaller food dish that she couldn't get into. .....then she laid an egg in the tiny egg food dish instead. She couldn't sit in that cause it's really small but she tried. I'd started researching egg laying by that point and again, the egg had gotten cracked, so I took it out.. and the egg food dish. (The egg food gets mixed in with their veggies and seeds now).
So there's nothing but perches in their cage now. There's an outside water holder, and a water bowl on the bottom for them to have baths in. .....yesterday Tap laid an egg in the water bowl. I don't know what to do.

Please help! Is there anything else I can do for her? We're even thinking of buying a larger cage and getting her a male singer so she can have real babies since she's so intent on breeding.. but then I'm worried about Raven and getting bullied in the cage. Eventually I'd like to have one of those large furniture aviaries and many finches.. but I never planned on eggs.
Thank you,
