Are any of these breeds considered "heavy" breeds?

[JamesC]

Here are the weights for the breeds listed by Spotted Cow - taken from the same source:

Andalusians 5.5 lbs
Anconas 4.5 lbs
Leghorns 4.5 lbs
Polish 4.5 lbs
OEG 4 lbs

While some people refer to them as "standards", they are all in the "Large Fowl" Class of chickens. The APA doesn't break chickens down by Light, Medium or Heavy weights. They are not all considered to be dual purpose.

Large Breeds of Ducks and Geese are broken down into Light, Medium and Heavy.

We have 17 pullets and 8 nest boxes and still they argue over a nest box or form a queue to wait, if that's the one they want to use.

Six of the nest boxes are 14 x 14 x 12. The other 2 are corner hay feed bins in our horse stalls (we don't have horses).

Sometimes one of smaller birds will jump in with a larger bird if she just can't wait till the larger one is finished laying!

We have one each:
