They have lived to a good age - 8 years I think. No sign of any problems, then on 21st November, I find poor Lulu, my white bantam silkie, passed away. Then yesterday, 24th, Mapp a lemon booted Sabelpoot popped her little sabelpoot clogs.
I still have Lucia (lemon Booted sabelpoot), Porshe, (porcelain booted sabelpoot) and my two young bantam silkies Buffy and Cordelia.
It seems to me that my chickens last much longer when I cut down on the wet treats, and give them daily corn treats and maize.
