I went out to a farm owned by a guy who was selling Rumpless Araucana pairs they were all over 1.5 years old, it was his breeding stock he was getting rid of to replace with younger birds and he offered to sell me his 2 year old 'prized' breeding hen for a good price and he told me she stills continue to lay about 3-4 eggs per week, I want to purchase her for breeding projects but do a hen's breeding chances decrease by year?
