My 7 month old Cuckoo Marans (who usually lays an egg every day bright and early at 6 am) has not been laying for about a week now, but still goes into the nesting box 2 or 3 times a day for about an hour at a time. Today I decided to put a fertile egg under her (from one of my other hens) and she just sat down on top of it after turning it for a while. Is she broody? My grandmother thinks she is too young to be broody--is 7 months too young? (she has been laying since she was 3 months old...) Thank you!
