Re: tracking info on breeding females

Just a quick post to see what info you might have on tracking your females that you breed. My question is this as you go year to year can you say for sure that your females do the same thing or close to the same thing year to year. I'm talking in reference to their ovy, building cycles and pre lay shed etc do they topically act the same way or can it be totally different year to year. Example-is their ovy around the same time,ovy etc. just thinking of the future and was thinking about starting a file in my computer to track all the info I have wrote down this year on paper. Thinking year to year things probably change. Am I correct in saying this . Any input would be helpful. Thanks
