Our 20 Hybrid RIR x White Rocks are 6.5 months old now. They have been eating 3 bags of Layer from TSC per month. Now they are eating a bag in just over a week! We get the crumble, which is $12.79/bag. It's starting to get cool here in the eves, calling for mid 40's these next few eves here in Western PA. They are drinking a lot of water, too. Is this a normal consumption or are they on a temporary feeding frenzy, preparing for cold weather? Or will they continue to eat like this? We have the 3 Roos and 17 hens, producing 17-18 eggs per day. This is our first flock and first fall with them Thanks.
