I have a few weeks until I'll have any that need the procedure. I brought all of the boys I had! I have some week old chicks that the cockerals will be my first solo attempts.
I have several that are the size of the 4 week olds but after doing that little white one, I feel that they are just too small. I think I will wait until they are a bit older, maybe 6 or 8 week size and see how it goes. Hopefully it will be somewhere in the middle of the two I did. LOL
