We have had our white leghorns for 15 weeks and they were 2-3 wks when we got them so they're 17-18 weeks. 3 out of the 5 have large red comb and wattles. I put a egg filled with dirt and pebbles in each box. They don't squat, they're skittish anyway. I can fit about 2 fingers between Fiona's(the oldest) pelvic bones. When can I expect an egg? This is them today. Amelia, 3rd oldest Clara on left, Fiona on right.
