Once the babies are born, allow the mother at least 3 days alone with them, without being disturbed. This allows mum to become familiar with the babies.
Then, providing mum doesn't mind you coming near the babies, you should move all the babies & the entire nest into a new cage at once. Make sure to place some old bedding in the new cage, so as to lessen the chances mum will reject the babies.
At three weeks the baby mice are not fully weaned from their mother. You should keep the baby mice with their mother until four weeks. Then separate the boys and girls. The girls may be housed with their mom.
Guinea pigs should be kept in a moderate temparature preferrably indoors. This should prevent field mice from getting into the cage. If you have any trouble you can always buy a new cage and set it up indoors.
You have to look at the tail. Squirrels have bushy tails. mouses have thin tails.
It is not a good idea to add more mice into the cage, especially adult mice that she does not know! But adding additional newborn mice is a common practice. The sooner, the better, and put the new additions behind her back, so she will think that she delivered them! Do not add any more baby mice when her original litter has started growing "peach fuzz." At the peach fuzz phase, the babies will start to have their own distinct odor, and the mother will instantly recognize which babies are hers, and which aren't. If she smells babies that aren't hers, she will eat them.
Yes, you can move your budgies to a bigger cage with their baby still in the nest, but it's important to do so carefully. Make sure the new cage is appropriately equipped with food, water, and nesting materials. Ensure that the new environment is quiet and stress-free to help the parents adjust. Monitor them closely after the move to ensure they continue to care for their baby.
For the most part, no - newborn puppies mostly sleep and and nurse for the first two weeks.
Newborn is two syllables: new-born.
To safely move newborn kittens to a new location, gently pick them up one by one and place them in a secure, warm, and quiet carrier or box. Make sure to keep them together with their mother if possible, and avoid handling them too much to prevent stress. Transport them carefully to the new location and provide a comfortable and familiar environment for them to settle in.
Sanitize the cage and get new bedding and the cage is good as new!
Newborn has two syllables. The syllables are new-born.
Buy a new cage and go to your hamsterz current cage. Then drag the new cage up to where you see another cage pic. (all stuff currently in cage will be moved to inventory)
If you're talking about a newbord dog the answer is neither. 3 kg is a bit below the average weight of a newborn human baby, which is way bigger than a newborn puppy. OTOH 10 g is down in the size of mice, which isn't particularly accurate either.
