We have 6 pullets, 5 (3 Ameraucana's 2 White Leghorns) of them are 19 weeks old the other is 11 weeks (RIR) One of the Ameraucana's laid her 1st egg on Sunday 6/12, she laid every day for 3 days, and hasn't laid the past 4 days. I heard once they start laying that they should lay just about every day to every other day. I started feeding them oyster shells. What else should I do?!
