I am at day 20 and the sacs in the 5 I have left are about what this shows as day 14. Floated them today and they were doing the backstroke so I know they are still alive. I dried them off and put them back under the broody but should I be concerned about them drowning in there. I mean what could be done at this late date to correct it any way? No pips yet either internal or external. Maybe tomorrow at day 21 hopefully.
