Quick question, we bought some new store lambs this weekend just gone. They need worming and Crovect, can I bring them in and do both treatments in the same day? Or do I need to wait a few days inbetween? They are 3 1/2 mths Texel x. My other lambs are up to date on wormer and crovect if that makes any difference... I'd like to get them wormed asap but also want to treat for flystrike asap too.
