1. What did you do
We didn't start building a chicken coop before we got our first chickens. Chickens were a planned impulse buy for us last year. Planned because we bought our house with the intention of having chickens someday. Impulse because covid made us finally decide to get them. We had ideas and plans, but then changed them once we actually had our chickens.
2. What were the consequences
Our chicks were in the house WAY too long

We loved being able to interact with them for hours and they are now all very friendly, but SO much "dust".
3.Did you fix it? How.
We eventually finished the coop after set backs due to weather and mistakes in the plans we bought - we should have followed our instincts instead of just using the measurements on the plans

. We also fortunately used a room that we were planning to strip and remodel anyway. Did I mention all the "dust"?
4. What did you learn.
Start your coop before getting chickens - only partially learned. We started to build a bigger coop this year(chicken math), but stopped due to the crazy wood prices. We ended up moving a shed instead. This years additional chickens were only inside a little longer than we wanted

Learned successfully- take everything non essential out of the room before adding chicks. And carpet, make sure there is no carpet
