Hello everyone. I have a question, maybe stupid, but here goes. I have a 1/4 acre pond about 25 feet from my coop. I used to have swans on it, so kept an aerator going 24/7 and just never turned it off when the last swan left. I now have thousands of goldfish and koi in it, so planned on keeping the aerator going thru winter to avoid fish kill due to not enough oxygen. My concern now is that my free range chickens will wander out on the ice and fall though near the aerator hole. This is my first winter with chickens. Are they smart enough to stay off the ice? I hate to confine them to their run for the whole winter, but don't want to lose any to drowning in an icy pond, either. Any advice? Thanks!
