Hi, I'm a bit curious as to what amount of hay is to be consumed by a chinchilla per day. I only have one boy, and he doesn't really eat his hay. At first I had him on Oxbow timothy and he was eating it normally, but then stopped. I thought the hay must have not been too fresh anymore, so I trashed it and went out and got a bag of Oxbow Orchard Grass. He loved the first few strands I gave him by hand, and for the first day or two he ate a bit more hay but then stopped again. He used to have a hay rack that goes inside the cage, and has a dish attached but I took it out because he would sit on the dish to reach the hay and end up pooping in his pellets. Now he has a regular hay rack that's on the outside of the cage, but its set low and he can reach all of it. But he still doesn't eat much hay. What's wrong with him? He does eat pellets and drinks a lot of water and his poops are normal (small, dark, not too dry or wet). He hasn't lost weight either, he's actually gained weight this past month. Help?
