My 7 year old hen, Janice, has gone broody for the first time. Her partner in crime/bff, Jessie, died about four weeks ago. Janice seemed fine at first, but about a week and a half ago I noticed she was hanging out in the nesting box exclusively. If I try to pet her she puffs up, "yells" at me and tries to peck me. I have never had a hen go broody before. I want to get new chicks and I've read I should wait 21 days before I place the chicks under Janice. My concern is her age. Should I still let her sit that long? I know she must be lonely but I also don't want to rush nature and have her reject the chicks. I do have a brooder, so if I need to I can take over for her.
