Signs females are ready?

[MrLang]

Ask what you wish, wanting to know what signs to be aware of during breeding season is a very valid question. If someone is tired of seeing your questions, they can always just skip them and there will be plenty more people here to answer.

Questions are good. Ask them. This ensures you don't 'learn yourself' by causing your snakes harm.

They can change behavior a bit, but if I had a snake start to get aggressive the first thing I would do is double check all of the husbandry and give them a thorough inspection.
