So I was going to bed and checked the ducklings. The Pekin is breathing with it's beak opened. Is this normal? And s/he's breathing really fast... At two weeks, s/he is gargantuan. Twice as big as the others - no other Pekins. When do we stop free choice feeds and get them on a feeding schedule? They are still inside in a brooder and get outside daily unless cold or rainy.
