That's really cool.
I put some pictures of a grackle nest in the photography section. The grackles continued to lay eggs and then abandoned the nest. The eggs never hatched
There was really nothing I could do for them, unless I bought an incubator, but really, did I want more grackles in my life or in my home. The answer was no. Even tho it sucked they abandoned the nest, I guess that is life!
