My hairless female has had 2 clutchs. The 1st clutch she had milk at 1st, then everyday we noticed the clutch was smaller. She went from 15 to 2 in a matter of 4 weeks. 2 lived in the end. The 4th week there was 5 they were under sized. I looked again 2 lived.
Her 2nd clutch she had 12 pups. She had some with milk bands some with out. 2 Died that night she did not eat them. She left them. I gave her babies to 2 other moms 5 lived. More would of if the timing was better. The other 3 moms I had each delivered 3 days after her. It would of been better if I timed it and had the other moms clutchs 1st.
Most of my moms cared for there own babies and had 15 all together. I know I have one great mom that had a clutch of 15 in her 1st breeding and she even tried to care for another rats babies also.
I now know to time the regular moms so the hairless can have her clutch after. You should make sure you count the amount in the clutch everyday to see.
I now also have a haired rat with the hairless gene now that I had give me 10 babies 4 which were hairless. We took my hairless male and breed him to a hooded normal rat. Then took one of the babies a female from that clutch and breed it back to the dad and got a clutch of ten. My hairless also have the Dumbo gene and double rex. So she had 6 hooded 2 of which were dumbo, and 4 hairless 1 was dumbo.
I have Dumbo rats I breed once in a while, Hairless 3 male 2 which are dumbo 1 of the 2 is a dumbo albino, ( 2 of the hairless are father and son. both double rex. The son was born dumbo. The albino has a patch of very silky fir on his belly and nose.) I also have 1 female hairless, 1 brown female normal, and 2 hooded. 1 with the hairless gene. I handle all my rats everyday or at least every other day. I have a few that can sit with me and don't wonder to far from me. Working on training.
