My EE, RIR, and brahma are 22 weeks. My SS is 20 weeks. My wyandotte, cochin are 18 weeks. Lastly my d'uccle and EE are 15 weeks. My RIR has had a blood red comb for 3 weeks and has been squatting for 2 weeks. My Wyandotte has surprisingly squatting for a week. My RIR, SS, and oldest EE have been practicing in the nest box for about 2 weeks now. They go in the nest box make a nice circle inside squawking and then leave. I've even see pretend nests outside the nest box as well. I've been feeding unmedicated starter with oyster shell to everyone, but the youngest two chicks. I give only healthy treats and supervise all free ranging. Granted it's been hot, but the last 2-3 days it cooled off, espically today. My EE, SS, and Cochin are super noisy too, especially in the morning. My SS comb is just turning red and her dark red wattles came in. How long do they practice in the nest box before giving eggs? I'm thinking any day now, but I am starting to lose hope. I've noticed my gentle speckled Sussex becomes a monster when in the nest box. If another chick walks up to her while she is in there, she goes after them like I never seen. I hope this is my magical week! The weather is in the 70's all week! It sure beats the high 90's-low 100's.
