During egg production, the male chickens are ground up and used as feed. A cockery is a mythical place you tell children that roosters go after when they are "discarded."
I felt a great disturbance in the cockery, as if millions of roosters suddenly crowed out and were suddenly silenced. I fear something terrible has happened.
"What's Tim up to these days? Haven't heard from him for eons."
"Oh, he's a cockery craftsman now."
"Ah great move! Used to tease about his member in swimming class, glad he has a good use for it now."
"Yup heard business is booming!"
Alright cocker, {or even alright cock} means alright mate? how are you? I have seen some {possibly} American posts on here saying cock/cocker is a rude name or derogatory term, it may be overseas but here in our nations capital {London} its a traditional way to hail a dear friend.
