Holly, a muntjac, was rescued on Monday by a member of the public.
The fawn was taken to Wildlives Rescue and Rehabilitation Centre in Frating Road, Thorrington.
A Wildlives spokesperson said: “She was rescued by a kind man who found her collapsed in the pouring rain in the open on a path along Clacton seafront.
“She was literally new-born with her umbilical cord still bloody.

“Sadly, the council had cut back all the bushes and undergrowth in the area, leaving no cover and nowhere to hide.”
The wildlife centre is nursing the tiny fawn back to strength, and will not be able to release it back into the wild until it is big and strong enough.
The Wildlives spokesperson said: “In 2019, wildlife centres had their licences to release muntjac back into the wild revoked. It is now illegal to release muntjac.
“They can be kept captive under licence.

“Wildlives is fortunate to have supporters with a magnificent stately home where the residents are deer enthusiasts and help us with our deer. They hold full licences to keep captive muntjac.
“The grounds consist of thousands of acres. We have taken multiple deer there to be released in one of their secure paddocks, hundreds of acres in size.
“Once ready, she will be transferred there under licence.”
Muntjac deer are common across England, and are also known as ‘barking deer’ due to their dog-like calls.
It is the smallest deer species in the UK.
