hello everybody, for the past few days ive been watching my buff orpingtons, they are about 9 months old, and theyll go into their nesting boxes and lay an egg and sit there for a very long time, ive been watching the barred rocks and and all my other hens and they all go lay their egg and theyll sit for 2-3 minutes tops and jump out and continue on with their daily activities. even when i remove the eggs from under the buff orpingtons theyll sit for about 2 hours and then i guess realize there is no eggs under them anymore and get off the nest. when i try to take their eggs they puff up and make that sound as if they are broody and peck at my hands, but my other hens dont do this at all they let me take their eggs with no problems at all. is this a sign of them beginning to go broody? or are they already broody? i dont know what to think of this because spring has begun and i heard chickens usually go broody in the spring when the weather starts warming up. please let me know what you think!!
