Well I have a hen sitting on 16 eggs, RIR, and she started sitting on June 30. So still a bit to wait.
I also had a LG bator given to me and I put 16 more RIR eggs in it about a week later.
So hopefully, I will have chickies hatching in a couple more weeks.
My almost 4 year old daughter is already planning a 'hatch day' party. LOL.
