Our broody is in the process of hatching out chicks and it occurs to me that our flock uses the TS rubber feed pans set up on concrete blocks for water. We will of course have a chick waterer on the ground for the babies, but do we need to worry about the chicks jumping in and drowning? Should we put a brick or something in the middle of the pan? We have 3, so we can also put less water in each. They never come close to draining the water even on the hottest days. How long would we need to worry about the babies? This is our first broody, so all our previous chicks were 6 weeks old before they used the feed pans for water.
