My proud gems are nearly 3weeks old. I noticed that they are trying to perch on a bit of wood on the ground. I have rigged a mini one up in the coop about 1inch (no higher) of the ground Just curious as to when they will start to jump up on the perch at night time as they still sleep in the nest on the ground with mum, and unfortunately we are having many flood warnings where we are which equals sleepless nights.... can chickens swim?!
