someone told us..get some more wearers before the others go..this way, you are not looking at an empty pen
I would say that depends on a few things....
do you want to keep more over winter when it isn't as pleasant?
is the meat just for yourselves or do you plan to sell it? (with another couple of weaners thats a lot of meat)
Have you got more land? It may be a good idea to rest their patch for a few months
If you are happy with all of that then go for it
