"Jack of all trades, master of one" is not necessarily a derogatory description.
On the contrary, it describes someone who can turn their hand to almost anything with varying degrees of success.
Even though they are not experts in any one particular field they are certainly valuable to have around.
Are you aware that there is a chicken breed that certainly qualifies as "Jack of all trades?"
Even though it is "master of none" the Buckeye Breed is a perfect representative of the age old saying!
Buckeye chickens were developed and bred in 1896. Mrs. Nettie Metcalf of Warren, OH. Mrs. Metcalf crossed Barred Plymouth Rocks, Buff Cochins, and Back-Breasted Red Games to produce Buckeyes, appropriately named after the "Buckeye" state.
Buckeyes are unique in the American class of chickens in that it is the only breed to be developed by a woman and it is the only member of the American class with a pea comb!
Buckeyes are a dual-purpose breed (i.e. used for both eggs and meat, but not as efficient for either as a specialized "egg breed" or "meat breed"). Their plumage color is a deep, lustrous shade of red, comparable to the color of the Buckeye nut. Some say the shade of red is similar to garnet.
Buckeyes have yellow legs and skin, and with their pea combs are very cold weather tolerant.
Buckeyes also have a unique body shape: slanted, short but broad backs; very meaty thighs; powerful wings; and prominent breasts.
It is said that their body shape is very similar to the Cornish shape of the early 1900s, even though no Cornish blood was used in their development.
Buckeyes are very active foul and do best in free range conditions. They have very pleasing dispositions and for the most part are very friendly towards humans.
Finally, Buckeyes are good meat producers and good layers of 150-200 eggs per anum. They are very well suited to farmyard and backyard flocks.
In short a "jack of all trades and master of none"!
