I was a complete newbie when we decided to venture into chickens. Got a coop made, moved in our ducklings (2 rescues), got a rooster who was about 6 months older than my girls, and got my girls--all RIRs. There were 6 of them, but one died trying to lay before she was fully matured (only 15 weeks), now we have our 5. I thought everything was good. Not one of them seem sick, everyone is eating well, etc etc. The girls are now 25 weeks, and we still have not gotten a single egg. From what I have read, I know that's late. What am I doing wrong?
