The other day I walked into the coop and saw a couple of lumps sitting where a few of my hens are known to randomly lay eggs. At first I thought it was poop but when I looked closer, it was really two shell-less eggs. One was broken and the yolk was spilled out, but the other was still intact. I kept it in a safe place and am planning to incubate it when my next batch of chicks hatches on Tuesday (just put the incubator on lockdown this morning). I checked but didn't see any posts of people actually trying this, so I'll give it a shot and let everyone know how it goes. I'm thinking that it should make a "shell" for it, because experience has shown me that an exposed membrane like that will not protect against bacteria and an infection would kill the embryo. I saw a few other posts of people who fixed broken eggs; one guy who taped dented quail eggs and had a successful hatch, and another lady who put a coat of nail polish over the outside of a cracked egg and was also successful. Tape would probably be too hard for a chick to break out of, so I'm thinking nail polish might have to be the way to go. There is a a lot of risk with using nail polish, the main issue being the egg is covered in dust which means an uneven coat. Should I clean it and risk breaking it? Would that do more harm than good? Should I even make a shell in the first place or should I just incubate as is? I'm open to any and all suggestions!
