Killdeer nest

The nest was found when we were preparing the hoop house for this years tomatoes. Any time we were close to the nest, the killdeer would call adamantly and when we were very close it would go into the broken wing act. Marking the nest, to be sure we would not accidentally step on it, i then proceeded to find out the gestation period in hopes of seeing the hatch lings. Three out of the four eggs hatched. The forth was infertile. After the first chick hatched, some of the interns on the farm went up to check out the babies. They said that they found two hiding under the dandelion leaves. After the third one hatched, we have not seen them since. There is about an acre of crimson clover and rye a few feet away from the nest.
