Congratulations on the new foal born 6/6/12!
I had a chestnut TB gelding, that was born 6/6.
He was named Mr. DDay. He'd been bred to be a show hunter.
Re: the chia seeds: they do sound promising.
But the seeds are very, very small: one thought I had, was they might possibly be inhaled, posing a danger, to lungs and airways, so moistening them before feeding would prevent that.
