I bought a pair of American buffs about 2 weeks ago and they have 4 eggs laid but its been almost a week since she laid her 4th egg. Isn't this a bit long between eggs? she laid the first 2 eggs 2 days in a row then waited a day and laid the 3rd and 4th egg the next 2 days. Can someone help me understand what is going on with my goose? Thank yall so much.
