That roo looks mad as a bee!
How truly odd that you've posted this. Today when I went into the coop to check on my 6 week olds, I started counting....1,2,3,4,5,6,7,8,9,10....
um....do over..1,2,3,4,5,6,7,8,9,10....OMG WHERE'S 11?!!! Then I hear this knock knock knock. I'm looking around behind the bag of rice hulls, under the roost, up in the rafters...knock knock knock. My DH says lift that sand pan. I do and there's number 11. That little pink pan that says "bath" against the wall, it had flipped and number 11 was under it.
Just today! See how odd it is that you've posted this! I'm glad you found your hen. That could have been so bad. Another chalk one up for her roo!
