Eggs are very high in cholesterol and it is not recommended to feed them to baby rats. Even adult rats should only be given cooked eggs on occasion, not as a regular part of their diet.
One week
You should only give your 5 week old baby gripe water and breast milk.
it takes about a week or two if it dose not hatch then something is wrong
about once a week
You should give an 8 week old baby 3 oz bottle of breast-milk or powdered milk if he/she has trouble drinking it then only give it 2
A little prune juice will help. Only a couple of spoonfulls. If your baby takes a bottle, just mix it into the formula. Don't give the baby any medicine.
4-5 eggs a week
no she will abandon them where they will die because they need her to feed them Do not listen to this person, this is absolutely not true. Baby rats must be handled regularly from the first week they are born or they will not be tame. If the mother rat trusts you she will be fine with this. A female rat will only abandon one of her babies if it is a runt and she already has over 12 babies.
not too much, too much will give him/her a mega stomach ache
For raw feeders, the typical rule is once a week. But I would imagine the same rule applies for cooked eggs too.
rats
