I like your chicken tractors - I am going to have to build one for my Banty Buff Cochin roos as soon as the snow melts - that might be in July here in NW Ohio!.......I just hatched out 20 NH babies - well the eggs were all from my NH hens - but some little banty Cochin roo got to my hens and I now have 3 little fuzz butts out of 20 that have feathered feet - now I KNOW my NH's do not have feathered feet!!!! I just never thought the Cochins could get to the NH hens, now I know better - they really have a big attitude, don't they?! Now I have some strange breeding and not sure what they will look like when they get bigger or what I will do with NH + Cochin chicks!
