At 6 weeks I checked and had 4 girls out of 13. At 8 weeks, I have 6 girls. They can be sneaky.I had to clean the brooder again, and Duckling caught the chicks. She checked their chests, and told me if they were boy or girl. I might only have 2 or 3 girls.It’s what I hoped for, but it means I really do need to keep them inside a while to ensure I can get fertile eggs to breed more, to set more, to get more girls, to get more fertile eggs, to set more, to get more girls...
