Hi Tamsin
Gosh I can't believe ours once looked like that! our ones are 17 days old now and have lots of fur, big ears, etc...
I had awful trouble feeding to start with as i couldn't get the hang of the syringe, got the milk everywhere apart from their mouth! i use a 1ml syringe which is long and thin and the bunnies seem to prefer it better than the 2.5ml one which is short and fat. it took a few days for the bunnies to take the food with ease, it used to take anything from 45mins to an hour and a half to give all four just 2ml. Now they are taking about 9ml each and it takes just about 5-10mins max each rabbit.
i didn't use a teat as i kept being told about the bunnies breathing milk into their lungs if they took too much milk in at one time. with the syringe you have more control. i practised using the syringes by filling them with water and dispersing it into a bowl!
guidelines for feeding which someone from here kindly gave me the link to is;
A baby rabbit of 1 day old would consume on average 2 mls of milk daily. By 5 days the volume would increase to about 12 ml. At 10 days it would increase again to about 15 mls, by 15 days increasing to 22 mls, 20 days increasing to about 27 mls, 25 days to about 30 mls. By 30 days of age you will expect to see a decline to about 20 mls, and by 35 days a rapid decline to less than 5 mls or weaned altogether
mine our 17 days and are taking between 21-27 a day now.
i hope this helps! we're in the middle of operation bunny at the moment as they keep jumping out of the cardboard box they had so transferring them to an old chinchilla cage someone gave me. partner in the hallway with his tools making a few alterations as we speak!
