Ive jst been out 2 H & H, bought a new bag of hay for them 2day. Its meadow hay, from the same shop that i normally get and it's the same type, but it's really coarse and sort of brown coloured. The bag I bought 2 weeks ago was lovely and soft and green. Is the brown stuff still okay 2 use? They still seem 2 be eating it, but it's taking them longer 2 munch a strand.
