I rescued a pair of chins a week ago. They said the female was 2 1/2 and the male was 1. I asked if she had been pregnant and they said no. They told me they had them for 6 mos. I noticed the male attempting to mate so I separated them bc I'm worried if she may already be pregnant and from research, I'm afraid of breedback. I'd like to know if there's a way to tell if she's pregnant or not, that way I can either put them back in the same cage or if I need to be learning about proper handling, bathing, and housing of pregos and babies!!!
