Couple of questions about the Oviposition perk

[Keraxos]

1. How long do you have to wait before eggs start coming in? I've tried testing it but results are a bit mixed.
2. Does fertility or incubation speed affect this?
3. If I gain the perk and then drop my avian features, will it still work?

Luckily enough for you i just went through the perk and updated in the perks page.
1) As long as your not infertile and not otherwise pregnant you should at longest have 30 days between each Ovilium pregnancy
2) fertility shortens the time between each pregnancy and i believe incubation works as normal
3) You should retain the perk even without avian features
