Hi, I've been reading previous posts on feeding olive oil with bread and messaging the lump to break it up but how much oil and how many times a day should this be done? Penny is 18wks old and seems healthy and energetic. I checked it and is not red or sore and she has had it for a month. I just started her on layer mash and she eats greens daily, my other girls don't have a lump in the crop.
