Hi all, Long term reader of BYC and new question asker. I've been keeping chickens for around 5 years now and haven't seen this behaviour before. Recently one of our hens has started spending all day going up the ramp into their coop and then coming out and going down the ramp. Do chickens get early onset senility? It's almost as if she gets to the bottom and thinks "What was I doing? Oh yes, going up the ramp". When I throw scratch in she races with the others and seems to eat and drink normally. She also wont allow any hay/straw to stay in the nesting box - it all gets scratched out every day. Egg production is a little down - instead of the usual 19-21 per week (3 hens) we're getting 15-18 per week. Any thoughts? Thanks for your wonderful insights!
