Props to those that decide to keep their birds in their houses - I for one, couldnt do it because no matter what - they do smell, no matter how much you change thier litter.
When we got our 6 girls (RIR's) from age 1 week (they are now 7 months) we kept them inside for the first 6 weeks of their life (got them in March and it was still very cold here in VA, so they had to stay inside). In my dining room in a dog kennel with a drop out bottom for cleaning. I changed the pine shavings every day, sometimes twice a day if they got really bad once they started to get a little older - and no matter WHAT - they smelled.
I didnt think they smelled either (and I am very very particular about smells, my cat cant poop without me scooping it right away out of the litter box, my trash gets emptied quite a few times a day *I should have stock in Hefty!
*), so when I couldnt smell them any longer because I was cleaning their cage every day, I thought "ahhh..okay I just smell pine shavings, not too bad, reminds me of a Christmas tree" WRONG! Our neighbors from church came over and walked in our front door (which is 2 rooms away from where the birds were kept) and said "Oh..you still have those birds in the house?" (they werent peeping or anything...hmm..how did they know?) I said "uhm...why?" They commented, although nicely "We can smell them.." I was mortified on the spot!!
I told them all I could smell was the pine shavings and they said "oh no dear, you absolutely can smell the birds above the shavings - its the feathers, not so much the poop, birds have a smell about them, foul smells".
The next day - those birds were outside in my garage (at this point, they were nearly 2 months old) and while still cold outside, until they reached 8 weeks - they lived the last 2 weeks of their lives out in the garage and I must admit - my house DID smell better! The garage smelled, but...at least it was detached. My neighbors were correct - birds just smell. Ever walk into a pet store? its that type of smell - you just grow accustomed to it and dont notice it as much - sort of like a smoker gets used to smelling smoke but a non-smoker can pick up on it right away.
JMO....but good luck with it all, I know alot of people do keep them inside and enjoy it immensely. I'm just not one of those people.
