Hi I have 2 gulabi does. I bought them last year when they were only 3 to 4 months old. Now one of them gets stronger and she was going in heat for last 2 months so I bred her. Whereas the other goat is not strong whereas both are given same feed. And she is also not going in heat. Her teats are also smaller than the other one. My main concern is why she is not going into heat?
