I bought standlee Timothy compressed hay bale (50 lb) for the first time; there were brown mixed in throughout as well as dust. It smelled musty too, not sweet. I have three rabbits, and they barely ate it. The quality is very different from the 10 lb Standlee Timothy I buy from Amazon. Can you guys look at the picture and tell me if this is good hay or are my rabbits too picky? Thanks! I was also told by a store manager at Tractor Supply that hay that looks vibrant green were dyed to be that color to attract the rabbits. Is that right?
