Don't worry too much about it, males are like human men, very happy for the sex but don't want to be up all night feeding or teething etc... lol
I did something totally different with my first pair that breeded, because the nest box I gave them, was made of perspex, so I could see everything that was going on. My girl went in and laid her first egg & then basically spent 23 & 3/4 hours sitting on it, before coming out for 15 mintues or less to get food, drink and poop. As they make the eggs out of their own body resources, just make sure she has enough to get, when she needs to fill up. As for the poop, it's bigger because she waits until she has to go, before then leaving her egg(s). So while she may normally do 20 small poops, now she has one big one, so don't worry about that at all.
I loved watching what she did, because she was so gentle with the eggs and with only four in total, she still found it incredibly difficult to cover them all & be comfortable doing it, so she was having to move the eggs around so that they all got decent coverage. My male went in to the nest, the first time she came out. He looked at the only egg she had laid at the time, went over to it as if he was going to take a turn, realised it was uncomfortable & left, to let her do it all. While I couldn't allow the eggs to hatch as I don't have the room for extra birds, as my custom bult cage is indoors & not an aviary, I simply waited until she came out to have a break & changed her eggs, with fake ones. She went back in & tucked them under her again, but after a few weeks, she realised they weren't going to hatch & gave up on sitting on them, or even going in the box. I've now replaced the male with another female & while they both still get horny many times each year, they aren't laying eggs so all the issues that come with that, have also gone. All I'll state, is that people should be aware that if a female is in breeding season, don't stroke her back under any circumstances. I didn't realise that this was turning her on & that in turn, meant she laid more eggs even though they were never gonig to hatch. Once you get babies & can take pictures, it would be great to see them. Good luck
