The general gestation time for goats is between 149 and 155 days. Below is a chart with estimated kidding dates for 149 day gestation. Look up the breeding date in the table and look to the right for the 149th day from the breeding date. We start to closely watch our does from this date. Does with multiple kids seem to kid earlier in the 149-155 day period while does with fewer kids will be kidding later in the period. We have had some kid earlier than 149. A doe generally needs to be at least 141 days into the pregnancy for the kids to have a decent chance of surviving.

Below is a sample of a spreadsheet we use for tracking our does to be bred and their kidding. It allows us to sort by the following
