I've 2 orphan lambs who are a week old today. Hay and straw plays up my kids noses, can we bed them on sawdust? What are the pro's and con's for each? I use sawdust for hens as its much easier to pick up muck day by day rather than cleaning out all the hay every day or so and am thinking it would work best for me to do the same for lambs but don't know if there's any reason why i shouldn't!?
New at lambs but enjoying their company loads, like having more kids but without the hard work!
