Thank you for the reply.
At what age are you applying the spiral bands with the "largest" bands?
Mine are about 4 1/2 months old now. I banded them at 3 months. They are Buffs & BA's, so they have large feet/legs anyway. I've had these on chickens that were 3 yrs old with no problems. I also don't free range, so if they get it caught on something, they are in the yard and easy to spot.
I totally get the "switching chicken colors instead of bands/etc.". But...to get my numbers (after cats and cats and dogs) killed me down from 27 to 6 back up to 27 I had to beg, borrow, and steal some chicks (I didn't really steal any...but some were given to me). So, I have 6 WLH (white leghorn), 1 RIR, 10 BO (ALL preceding 17 animals are female), then 2 BR (barred rock) roosters, and 10 Americaunas of mixed sex which look like at least 3 males so far. Um, it's a motley crew to be sure. :-/
All I can suggest is when you buy young chicks again, buy something that you don't already have. Then when the "motley" crew are ready to cull, you can get another kind of chicken different from the previous years baby chicks.
Color coding from year to year isn't really in the cards; I won't cull any of these (except males who can't mind their manners). Plus, in my rural area, the market seems kind of low (not a lot of buying or selling traffic) so I'm feeling kind of stranded. Furthermore, all I need are birds which turn useless bugs into useful eggs; I'm not breed specific or oriented.
I don't understand the bolded statement. In your first post, you said you would be culling at 2 yrs of age. You also stated that you wanted to mark them, then not have to worry about it.
You have a good idea, but I'm not feeling it will work for my goals (at this time...I'm learning...)
Thank you again.
