For instance, doesn’t poultry (chickens, ducks, etc…) lay eggs but they only hatch if a male fertilizes them? However, does a female chicken mate with a rooster to produce eggs or can you have eggs without a rooster? My male and female cockatiel are ALWAYS breeding and I let her lay 2 clutches back to back but it’s too stressful for her to have another clutch so I’m taking the eggs out (I removed the nest box). However, she continues to lay eggs in her feed dishes. So far, she’s laid 13! I’m worried. SHOULD I REMOVE THE MALE? Would she stop laying eggs ’cause she isn’t breeding or is she like a chicken and will lay eggs regardless but they won’t be fertile? I’m confused! I think a lot of people wonder the same thing about chickens so it’d be nice if someone out there know A LOT about all birds in general. THANKS!
