On October 22nd I picked up three female chins from a lady who had decided to stop breeding (Two of my pet chins I bought from her 3 years ago.) She had sold most of her herd, aside from the few she was going to keep. She had some unfortuante family issue arise and could no longer keep these three females. when I picked them up she told me that the standard 10 year old female had been separated from a male on july 26th. When I brought them home I weighed them and put them in a baby safe cage just to be ready in case. I waited untill today to move them into a bigger cage, two weeks past her last possible due date. Before transferring them into a bigger cage I decided to weigh them. The 10 year standard has gained 20 grams, the 2 year old beige has gained 23 grams , but the 9 month old black velvet has gained 106 grams. I called this lady and asked if the BV was ever exposed to a male and she said no. she said there is no way she could be pregnant. She told me it is probably just her growing. She was feeding PRCS, and I do also. The only difference in diet is I feed loose hay and she did not. I dont have much experience in younger chins. Could this weight gain be from her growing or should I just keep them in the baby safe cage untill 120 days from the day I got them? I cant imagine she would lie to me, but I'm just worried.
