Hens produce eggs without roosters. That's your alarm clock though, I say keep it if you can, your sleep pattern may change some day. Besides, baby chicks are one of the cutest pets we could have.
So, I've had a short dream while I was falling into deeper state of sleep the other day, a dog peed on my face! I resisted it but the story was already written, I didn't smell it, I didn't feel the warmth nor it didn't get into my mouth, I got over it soon after I woke up. I was pretty aware during that dream, thought I could do something about the insult that was coming. How was I able to sleep soundly after this dream though?
DUCKs! They can be good pet too and can be very friendly, and supposedly they sleep with one eye opened, because of the instinct to protect oneself from predators, or as one pet duck owner puts it, she never catch them sleeping.
Some says he wrote in the morning and he was a notorious night owl. Whatever he was like as a sleeper, his work contributed to the advancement of sleep medicine, awesome stuff!
