I'm talking about cockatiel eggs but I'm pretty sure they are all the same. I took them out the other day to candle them and two of them had cracks on them- dents- bad cracks- not hairline. It worried me. One wouldn't move I wasn't sure if it was alive or not. THe other was moving just fine. Today I looked again and they both seem to be moving- one less than the other. Could these cracks cause deformities? It's been at least a week since the cracks happen and they are still growing so I think they will live, I'm just worried something will be wrong with them. Their due dates are the 18 through the.... 25ish (OMGosh that seems so close!) I've seen the nailpolish idea and the papertowel idea but I'm scared the chemicals will get into the egg and harm the babies. I don't want to do that.
