There is an extreme size difference between the hatchery and good show stock minorcas here. Almost as if they were bantam and largefowl versions. you have brahmas- the show minorcas I saw were as big as them, just longer and narrower in body with big combs and tails which makes them look even bigger. the brahmas probably weigh more though...
due to my allergies I very rarely handle the birds so I don't know if the barbezieux are heavy.. will say they look just tall, not really heavy looking. I keep meaning to weigh several of the birds for possible culling.. will try to remember to weigh the "barbies" that day too.
as for eggs, they are medium-smallish.. someone with older birds told me they lay big eggs but I am not seeing big eggs yet. They arrived as big day old chicks(taller and bigger than say, barred rock chicks) so maybe they do lay bigger eggs. the eggs are tinted, btw.
by very minimal handling it is easy to recognize which birds are naturally(genetically?) tame or wild. For example there is an EE picked up on the same day as the hatchery turkens... all of the turkens were calm, with two being very tame, right at my feet looking up at me(I probably could have tamed her to be a lap chicken like Fire Ant's Sweetie) while the EE is usually staying as far away as possible and panicks if she thinks I am going for her. Couldn;t be any more difference between her and the turkens despite exactly the same age and care.
