I have a 1 yr old ISA brown and for the last few days she has laid around a lot in the run. At first I thought it was the heat and I knew she was eating and drinking, but hadn't been free ranging with the other hens which is very unusual for her. Well this morning I went out to check on her and gather eggs and she is alone in the dog house I have set up for them and she is sitting on a pile of 4-5 eggs and wont get off them and pecked at me when I tried to get them, again very unlike her. She is always the fist one to come to me for snacks and attention. Is she broody? I have never had a hen go broody so I have no clue what the signs are. Any help would be greatly appreciated.
