So last night I noticed what looked like a piece of wood in my guinea pigs hay, I wasn’t sure where it came from so I took it out and threw it away. Then this morning I refilled their hay and when I came home I found another (image below) is this normal to have in this type of hay ? I’ve never seen it when I bought it in the past(Oat Hay)
