I have six turkey eggs in my incubator due to hatch this week on the 21st. I candled them earlier this month and 5 of the 6 were developing and moving. The 6th was not fertile. I candled them last night and only two of them were moving. The other three were just black blobs. I like to prepare for the worst so my question is if only one of the eggs hatches, I would like to get a few more poults from somewhere to keep it company. What is the oldest age poult I could put in with a few days old poult? I have seen local ads for guinea keets for sale. Could I put some guinea keets in with the poult for company or should I only put other poults? Thanks!
