Thank you all for your replies.
Paige's info is good & I am trying to be positive for her as she picks up when I am not.
April seems to be managing very well, she is moving a little unevenly but is moving & really picking her hind feet up & stepping under. Yes the frogs were a little overtrimmed - I think he wanted them to look tidy, as farriers do. However, I just let him explain everything he was doing & show me, & to his credit he said that the frogs were not in contact with the ground, so they were not doing their job. Not sure why he trimmed so much though.
She is very bright in herself & lying down alot less now. I have put her back out with the others; we have had little rain recently so it is not slippy & I think is providing her support when the ground moulds into her feet each step. She doesn't care for racing around with them & mentally it has to be helping her recovery. Apparently she doesn't need her boots on to go out either - the dominant mare knows her own mind!!!
Given the response to her trim, would it be ok to start backing her toes a little, perhaps every couple of days, or should i just do it all in one go?
I have photos of the others' feet, do you want them all emailed to you Lavinia? There are a few....
Many thanks again.
