I have two out of four hatched, this evening late is day 21. They are my first F'5's from Kathy's F'4's

These four are from the smallest pullet but correctly coloured hackles/tail and that had white legs as a chick but are now are a light yellow. Not as deep yellow as the other 3 pullets or 3 cockerals I am using. Will be interesting to see how they grow out for sure!
Scott, if you would post pics as they grow I would love to see. In the fall I may cross one of these Delaware cockerals over my New Hamps (came from Luanne D'Amico who I think got her start on them from Kathy) to try to speed up their feathering/growth. The F'4's were very slow to develop, I think I had mine in the brooder for 7 weeks before they were fully feathered. My other breeds are ready to go out at 4 - 5 weeks.
