Sure they're cute when they're babies

.....but...
Be ready for noise and stink.
The smell of wet feathers and guano after a warm rain will linger in your memory for years.
Throw away the alarm clock, the early morning feedings will wake you with a cheerful serenade
You said you have pigeons?, I hope your experience won't be as bad as mine.
We had some starlings nest in my attic space a few years ago.
The parents crawled into the bathroom exhaust tubing in the attic, punched a hole through a joint in the solid aluminum vent and set up a nest in the blown pink fiberglass insulation.
We had no idea they were there until we heard the nestlings chirping away in the bathroom vent. The cats didn't know what was going on!
It wasn't too bad until it rained and the smell would waft its way down into the house. ugh!
We left them in peace until they flew away.
I had to dig through 2 feet of fiberglass to get to the nest and I was amazed at the comfortable little home they set up.
I put a ball of chicken wire in the vent entrance to block them from coming next year. Sure enough, next spring there were some angry starlings trying to renew their quest for the nest.
