Chicks in following image are doing another activity that suggests to me they are weaned. They are loafing together in a clump without mother. This occurring when ambient temperature was 54 F so not overly warm. This is evidence I need to clean garage tomorrow. Second shows father and mother in close proximity to other chicks. Father is preening. We may have a louse problem which is to be expected when so many are roosting together in same spot every night. That will self-correct as soon as chicks start roosting up. Chicks now starting to get aggressive in their own right and can now as a group drive off a mixed group of Ancona Ducks and Silver Sebrights despite latter having males already crowing. Their parents still back them up.
