yes, they feed there young milk and do not lay eggs.
I have never heard of any species that can do both. One would assume that a creature would either lay internally fertilised, (or unfertilised) ova in the form of eggs, or produce live young. For a creature to do both would be most unusual.
No, they are a bird. They do not have hair. They lay eggs and don't give birth to live young. And they do not feed their young milk.
Frogs in general do not feed their young. Once they lay the eggs, their job is done. The eggs hatch without intervention from the adults, and the young tadpoles must fend for themselves. Tadpoles feed on aquatic vegetation which they hide among.
No, amphibians do not feed their young with milk. Some amphibians lay eggs that the young, called tadpoles, hatch from and then develop on their own without parental care.
They don't! Most amphibians are generally independent from the moment they are born. However some, such as the worm, feed their young their own flesh. Amphibians do not feed their young. They lay the eggs in water and leave them to fend for themselves. They are also quite likely to eat their own young. That is why they have so many eggs.
Mammals do not lay eggs. They give birth to live young and feed them milk.
Badgers are mammals and they give birth to live young.
Penguins do not have fur or give birth to live young or feed their young with milk, so they are not mammals. They have feathers and lay eggs so they are birds.
No, they lay eggs, they have feathers and so they are birds. The special things about mammals are: --they bear live young (don't lay eggs, except in the case of the platypus and the echidna) --the females make milk to feed their young. --they have hair or fur.
She is either too young, too old, injured, not being cared for properly
No, not all mammals breastfeed their young. Some mammals, like monotremes (such as platypuses and echidnas), lay eggs and do not produce milk to feed their offspring.
