Only if they are too closely confined/overcrowded. In fact, overcrowding and close confinement can cause almost any animal to become cannibalistic, perverse, brutal or at least aggressive, even humans.
My Heirloom medium sized Early Girls have just yielded me my first few dozen of the season. The big monster Beefteak slicers about another month. The Romas in about two more weeks. They are uncharacteristically huge for Romas.
Memphis is very hard to grow tomatoes. Too humid. Too hot. Night air too still and wet. A lot of fungal nightmares. This season I put large barn fans at the rows that I turn on at nights to keep air moving down the rows. That has made a big improvement. I turn them off after the morning dew burns off around 9AM. Then back on at 10PM.
Well. That explains it...
