Naked necks are highly recommended in France.
We usually have Hubbard/Cobb cross but I've not been across to my usual supplier in Cornwall this year. To tide us over we went to the local Couvoir as they raise these only to find that they are 'order' only and had all been shipped out that morning. We chose (for 79c each) 5 black and 5 brown naked necks. What we didn't know is that they 'give' you extras (left over from that day's orders) and ended of with 26 chicks of 5 different varieties............................. Over half, luckily, are cockerels and all doing nicely...............
I'll report back later in the year with the results of the roast chicken test!
