I let my chickens out to freen range each morning and put them up in the late evening. They have adapted really well and enjoy meandering around during the day pecking at stuff. I always give them feed in their pen in the am when I let them out and I feed them in the evenings when I put them up. They go back to their coop to lay egss and everything seems to work beautifully for them and me. However this morning when I gave them feed they were ravenous and acted like they haven't had feed in a hundred years. Not sure about this as it has never happened before. They are usually more eager to get out and free range than eat in the mornings. Could it be due to the fact that the weather is starting to get a little cooler or could it be due to something else?
