This shouldn’t work should it? My 2 Cockerels are from eggs I incubated. Only 4 hatched successfully, 1 just stopped developing at 3 weeks and died a week later. Another was always stunted and died after a month. The other two, a SL Wyandotte and a BC Marans both turned out to be male and magnificent they are too. I had six SL Wyandotte eggs and 3 hatched. I had 3 BCM eggs and only the 1 was viable. 2 out of 9 is bad I know. But I’d never done it before. I was at a local market here and bought 3 Black Star hens for 6 Euros each. Never worth trying to hatch them for that. At this stage I didn’t know if my chicks were cocks or hens. I would love to get a Wyandotte hen or 2 but am afraid of upsetting the status quo. My SLW is a sweety and apart from the 1st thing in the morning chase he and the BCM are the best of friends and are always together. My chicks are pretty much free range.
