The smaller of my two twins has a yellowy back end, poo isn't too thin and watery. Lamb is suckling well, seems bright, alert, full, etc. Ewe and lambs have access to a pen and can go outdoors into a makeshift paddock. She is my only ewe lambed hence why she isn't out in the field set aside for them yet. The other lamb seems okay. Should I be giving the lame glucose as a precaution?. Pens are clean, were well disinfected, and bedding is dry. Gloves were used to handle lambs and wellies are disinfected before going in with the sheep, I work with calves so everything is disinfected when I leave work and disinfected again at the sheep as a precaution.
Any suggestions?.
Edited to add: lamb was born on Friday evening without any assistance, and was the second one born.
