Answer: None of my reference listed the specifics of ostrich manure, but there are some general things about bird manure that most likely apply. First of all, bird manure is usually quite "hot", or high in nitrogen, and can indeed burn plant roots. I would compost it thoroughly first, before applying to the garden. Does your friend use any type of bedding such as wood shavings? If so, then this would be a good carbon source to balance the nitrogen in the manure--so if possible get the bedding too. Thorough, hot composting should take care of most weed seeds. You might do a "test" on a small section of your garden the first year to see how the plants respond. And if you are concerned, you can contact your cooperative Extension Service (ph# 315-331-8415) about testing the finished compost. I'm curious, can you raise ostriches in New York?
