Can someone tell me what to do? We started with 10 eggs, now down to 2. We're at day 23, but there is still obvious movement in egg with candling. Almost all opaque with chick, with air sac, just a 0.2cm area of clear with vein. Should we help them along at this point, or just wait it out? It's hard knowing they should be hatching, but aren't. Any one with any suggestions? Thanks!
