Sound proofing implies total containment, and no ventilation, and that's bad for chickens.
You can help reduce the noise level, but roosters do crow!
Indoors, and at least they are tiny!
Bummer. I guess it is better than 5:30 am like it is at my house. I sleep with a sound machine on, so it is not a problem for me, but it is not good if you have close neighboors. I personally love roosters crowing.Like maybe putting cork up on the inside. My Serama roos start crowing at about 6-6:30am which means they will have to be brought into the house every night until I can rehome them.
We made a wooden box about 2x2 lined it with egg cartons for sound reduction. Stuff about 6 inches of gay or draw in the bottom. Our lid is on the top, just a wooden lid with hinges its not snug at all just enough were the rooster can't pop on out. It has a spilt i the middle with lots of holes. We will be trying to improve upon the concept as our box hasn't held up as well.How?
what are the tiles like? Perhaps you can try them and report back.
