i had a blue jay hanging out, stealing food in the dog dish earlier today it was humorous watching the dog chasing it away from its dish. Later on he was flying around the black spruce patch across the street, suddenly two robins were freaking out, chasing him furiosly, he disappeared into the grove but robins were still freaking so I walked across the street, through the ditch & out he flew. The robins nest was just halfway up the tree so I peeked in. The Jay had destroyed one egg, the other three seemed fine. I removed the broken egg, put it on the ground & covered it with moss. I guess my question is shoulld I let nature take its course, since reading this & other sites, sounds like the jay will surely be back. I found an old stovepipe cover that could be wired, gently, on top of the nest. The robins could easily get in & out but very difficult for the jay to get in, or just leave it alone, pretty sure I'll hear about rules & regs, just wondering more about the interference & if they'd abandon the nest. Thanks
