There have been three or four days when I could swear I can tell that they've grown overnight. Today was one of those days - I realized they're not so much chicks now as they are average-sized birds that actually allow me to hold them. Amazing!

My little flock includes Pippa, a Belgian Mille Fleur d'Uccle, Ginger, an EE and three babies added January 2016 - Bella the BO, Ava the Australorp and Nugget, a RIR.
