Hello! I've a small flock of BR and BO (4 each), and they're 14 weeks old. They've started developing wattles and combs, which seem to get redder every day. Whe I built their coop, I sealed off access to the nest boxes to prevent pooping, etc. It will be easy to 'unveil' the boxes. Given the signs I am seeing and the age of the chickens, is it time to start thinking about opening access? No squats or songs so far. Thanks in advance for your advice.
