My chickens are approx. 3 months old and have recently started acting so weird. They are starting to go to the bathroom SO MUCH when before it wasnt that often, they are pecking at the back door to come in the house, perching on random things (pool gate, fences, yard lights, etc.) They have also started to seperate from each other (2 of them). Also, they are eating so much more! What could be going on? Are they old enough to lay? Im concerned for them! Any help would be much appreciated!! Thanks!
