You could just talk to them and clarify what kind of article they were planning on doing. Whether it was about how the circumstances of the Icy's were improved after the auction or if they are looking for a problem. More than likely, they would just like an update on how he has gotten so much better care after being auctioned than he ever had before. Plus, anyone who knows anything about horses would be able to tell with just one look at either Solon or at your stable that you really care and provide for them. So what if your stalls are improvised, they are safe and comfortable and they work. So what if your pasture is flooded, you have no control over the weather. Yeah, Solon may not be in perfect condition yet but it has not really been that long since you've had him and fattening up a horse too quickly from starvation conditions is much more dangerous than having them stay skinny for a while
By all means, if you are not comfortable with it, then don't do it but I think it might be a really good thing.
