Yep 4ft is fine I have a mixture of the 4ft sheep and goat fence and 6ft dog kennel panels... I like they both... But be careful with the 4x4 squares! Little babies can fit through at least my Nigerians can
I am looking to get the 2x4 fence to make a baby pen out of.. That way I don't have to worry about anyone getting stuck or out

I think it depends on the area you live in, and what kind of wild life you have around. I put a 6 foot fence all around the outside of my pasture cause of living in the country side and we hear coyotes almost every night. Also I have seen white tail deer jump a four foot fence very easily. But this is just my thoughts on fencing.

That is a very good point.. I dont always think of these things right away... I have to sit and ponder for a while lol!
