Went back to watch the video. Nice job! Some of us (myself included) are also somewhat new to raising pigeons, but there is also a wealth of knowledge here from the more experienced keepers.
If I’m seeing correctly, I think you have 3 blue bars and a blue checker?
And the ducks!!

Since the loft is so close to the duck pen, please flash over there on occasion too. I have lots of chickens, a few ducks, and now a small group of pigeons. The pigeons have quickly captured my heart, but I can’t imagine ever being without a few ducks.
