chickens getting squashed in automatic door?

[sydney13]

i am thinking of getting a automatic door, and was just wondering if it could every shut on a chicken? And are the predator proof? What place sells cheap ones, and and how much does a cheap automatic door cost

Mine closes very, very slowly. It's like it's in slow motion. I never worried about the chickens getting caught. It does keep predators out. Foy's carries the one I have, although I bought it from a different company. I've got the inside mount door with the external light sensor.

If you're looking for a cheap automatic door, you should look at the threads here on building your own. Just do a search.
