Oh yes, and about the numbers of birds per sq. ft.
The great Holderread himself points out these number for ADULT BIRDS.
Example 1. He says that for MEDIUM TO LARGE breeds a minimum of 2.5 to 3 sq. ft. of space is sufficient if they will only be sleeping in there.
Therefore 11 Muscovies (large breed) would be fine with a min. of 27.5 to 33 sq. ft. AS ADULTS.
And Campbells (small breed) would need even less than 2.5 as a min. So let's say 2. That would mean that 14 ADULTS would be fine in 28 sq. ft. MIN.
I plan on having that exact number (25 in all) living in 160 sq. ft. Clearly they are not overcrowded in the least.
Example 2. (note: this is Holderread and not me) One 4 x 8 coop is sufficient for 6 to 12 ADULT BIRDS AS A BREEDING PEN.
Now, a 4 x 8 is 32 sq. ft. The cage I am about to complete is EXACTLY FIVE TIMES THAT SIZE (i.e. 160 sq. ft.) So, if you multiply Holderread's "6 to 12 ADULT BIRDS" by 5, that gives us:
30 to 60 birds can be placed without overcrowding at all, in a 160 sq. ft. pen.
There it is, right from the great himself............
FINALLY, AS THE LINK I POSTED IN THE PREVIOUS POST STATES: IN THE BREEDING SEASON, THE ROWDY DRAKES WILL NOT BE IN THERE WITH THE GIRLS. THEY WILL BE IN BREEDING PENS WAITING FOR SOME PRETTY DUCKS TO COME ALONG.
