The copper black hen is Cinnamon. She seems a little nervous and has a bit of a baldy bum. The all white sweetie is Pepper - she has a very bare bum!
The Pied is Clove. She has a very bare bottom and a swollen abdomen. I've had three eggs off them today, I can only assume that it was nutmeg who has not laid, so Clove's tackle must be working OK.
As a precaution I've been out in the dark and given all their botties a good spray with ukadex - a foul smelling, tar based spray that deters pecking. Luckily for me they were all sat on the branches with their backs to me so I just squirted them while they slept! I got a good scolding for my efforts!
