Silent movie of Penny and Angel - Note Penny shoos Angel away - there's a change in hierarchy

Penny still needs more weight and she's suffering without the rug- but it's been raining on and off, so I took it off. Really not so sure what to do, keep the feed up and keep checking her skin.
Angel has some bloody spots from ticks. I am pulling them off by hand. Not keen on using chemicals on a pregnant horse.
